Description
PORTABLE OBJECT SENSING ASSEMBLY
This invention relates to an object sensing assembly for attachment to a frame
surrounding a vehicle opening for sensing a body part in an opening, such as a vehicle
window opening or a vehicle boot opening.
According to the invention there is provided an object sensing assembly for attachment
to a frame surrounding a vehicle opening to detect an object in said opening, said
assembly comprising:
a flexible seal member; a first electrically conductive member within said flexible seal
member; a second electrically conductive member within said flexible seal member
and separate from said first electrically conductive member; and vehicle frame trim
means for attachment to said frame; said flexible seal member positioned adjacent to
an inside surface of said vehicle frame trim means.
Embodiments of the invention will now be described, by way of example only, with
reference to the accompanying diagrammatic drawings in which:
Figure 1 is a diagrammatic side elevation of a motor vehicle;
Figure 2 is a cross-sectional view along line II-II of Figure 1 of the window frame with
a sealing and guiding assembly showing an arrangement of the sensing assembly
according to a first embodiment of the invention;
Figure 3 is a cross-sectional view along line II-II of figure 1 of the window frame with
a sealing and guiding assembly showing an arrangement of the sensing assembly
according to a second embodiment of the invention.
In the drawings, like elements are generally designated with the same reference
numeral.
Figure 1 shows a motor vehicle 5 having a front door 6 with a power-driven window 8
which is shown cross-hatched for clarity. The power-driven window 8 is raised and
lowered by means of a suitable motor, normally an electric motor, under the control of
switches positioned within the vehicle for use by the driver or passenger. All or some
of the other side windows in the vehicle may also be power-driven.
The window frame 10, forming part of the vehicle door, incorporates a window guide
channel 12 one form of which is shown in Figure 2. The window guide channel
comprises extruded plastics or rubber material which incorporates an embedded metal
core or carrier 18.
The carrier 18 may take any suitable form. For example, it may comprise a simple
channel of metal. The channel could additionally be formed with apertures to increase
its flexibility. Instead, the carrier could be made from U-shaped metal elements
arranged side-by-side to define the channel and either connected together by short
flexible interconnecting links or entirely disconnected from each other. The metal
could be steel or aluminium, for example.
Instead, the carrier could be made of metal wire looped to and fro to define the
channel.
The carrier 18 is advantageously incorporated into the extruded material by a known
cross-head extrusion process.
In this embodiment the carrier 18 is C-shaped, with an extension piece 28 extending
down from one of the arms of the C-shaped channel. Between extension piece 28 and
sidewall 44 is a hollow chamber 46. Advantageously, metal carrier 18 within the
window guide channel 12 where it runs along the top part 1OC of the window frame
(Figure 1) is separated from the metal carrier 18 in those parts of the window guide
channel 12 fitted to parts 1OA and 1OB of the window frame.
The extruded material defines a lip 40 projecting outwardly from a sidewall of the
window guide channel 12, a lip 62 directed inwardly into a glass receiving channel 14
from sidewall 44 of the channel 12 and a similar lip 38 on the opposite side of the
window glass channel 12 but of shorter extent.
The area 14 between window 8 and lip 38 of channel 12 is glass receiving channel 14.
The window frame 10 (Figure 1) may take the form of a metal channel which is sized
to receive the window guide channel 12 as shown in Figure 2. When the channel 12 is
fitted into position within this frame, lips 24 and 26 (Figure 2) overlap and grip the
outsides of the window frame 10, specifically lips 24 contact panel 22 of window
frame 10.
The window guide channel 12 extends around the sides and top of the frame 10. Thus,
it extends up that part 1OA of the frame alongside the "A" pillar of the vehicle, along
the top 1OC of the frame and down that part 1OB of the frame corresponding to the "B"
pillar. Where the window glass 8 slides into and out of the lower part 5A of the door
5, a waist-seal (not shown) is provided on each side of the slot.
The surfaces of the window guide channel 12, and of the waist-seal, which contact the
sliding glass are advantageously covered in flock or other suitable material to provide
a low-friction and substantially weather-proof surface.
The window guide channel 12 also has a portion 30 which is clipped into window
frame 1OC and also holds the window guide channel in position. Lips 32 and 31
contact parts of window frame 1OC to hold window guide channel 12 in position.
As shown in Figure 2, window guide channel 12 includes sealing member 52 and
sealing lip 50 on the outside of the window frame. Sealing member 52 and sealing lip
50 engage the frame of the door opening when the door 5 is closed, to provide a seal
around the edge of the door 5.
Figure 2 also shows vehicle frame trim 90 and flexible seal member 60 positioned
between window frame 10 and frame trim 90. Together these elements form the
object sensing assembly.
Frame trim 90 is made up of consecutive regions 92, 94, 96 and 98. Section 98 is
positioned in contact with upper part 1OC of vehicle frame 10, the next region 96 is
positioned adjacent to part 1OC" of vehicle frame 10 and continues downward and
then moves inward towards the window opening as region 94. Region 94 continues to
region 92 which extends upwards substantially parallel to window glass 8.
Lip 48 extends downwardly from sidewall 44 of window guide channel 12 and at the
bottom of sidewall 44, next to lip 48 is end wall 47. Lip 48 and end wall 47, along
with sidewall 61 of flexible seal member 60 define a trim receiving channel 100.
Region 92 of frame trim 90 is received in channel 100 when the frame trim 90 is fitted
to vehicle frame 10. When the frame trim 90 is fitted to the window frame 10, region
98 and upper part of region 96 may be simply clipped onto frame parts 1OC and 1OC"
respectively, or they may be secured to these parts of the window frame with further
securing means (not shown).
As mentioned above, the flexible seal member 60 is positioned between window frame
10 and frame trim 90. The construction of the flexible seal member 60 will now be
described in more detail, followed by details of precisely how the flexible seal member
60 is located between the window frame 10 and frame trim 90.
Flexible seal member 60 may be formed of the same extruded plastic or rubber
material as window guide channel 12 or a different material. It is formed as a separate
element which contacts and may be sealed to window guide channel 12. Seal member
60 may be sealed to window guide channel 12 by an adhesive.
Embedded in flexible seal member 60 are an outer electrically conductive member 72
and an inner electrically conductive member 66. The inner and outer electrically
conductive members are separated by hollow chamber 70. Wire 74 is located within
and runs the length of outer electrically conductive member 72, and wire 68 is located
within and runs the length of inner electrically conductive member 66. One end of
wire 68 is for connection to an oscillator which supplies an electrically oscillating
signal to wire 68 and one end of wire 74 is for connection to ground. Of course, the
connections may be reversed. The other ends of wires 74 and 68 will be connected
together by an electrical component, such as a resistor for example, to ensure electrical
continuity between the two electrically conductive members, when the assembly is
energised and operating to detect objects in the window opening.
Preferably, the inner and outer electrically conductive members 72, 66 are made of
electrically conductive rubber. The remainder of flexible seal member 60 is preferably
made from insulating rubber. Preferably wires 74 and 68 are metal wires.
Outer electrically conductive member 72 has a main body portion 78 and side portions
76 which extend away from main body portion 78 towards the inner electrically
conductive member 66. The outer electrically conductive member 72 is thus
substantially channel-shaped and the inner electrically conductive member 66 is
located on the opposite side of hollow chamber 70 within, and extending lengthwise
of, the channel defined by the outer electrically conductive member 72.
It is understood that the extruded plastic or rubber material of flexible seal member 60
electrically insulates the inner and outer electrically conductive members 66 and 72
from the vehicle frame 10.
As mentioned above, the outer electrically conductive member 72 has a main body
portion 78. This main body portion 78 is positioned within the flexible seal member
60 between hollow chamber 70 and seal region 80 of the flexible seal member.
Seal member 60 also includes protrusion 82, located on the underside of flexible seal
member 60 below inner electrically conductive member 66. The protrusion 82 is
separated from inner electrically conductive member 66 by a part 86 of the body of
flexible seal member 60. The ends of side portions 76 of outer electrically conductive
member also meet part 86 of flexible seal member 60.
In this embodiment of the invention, region 80 of flexible seal member 60 contacts
part 10C" of window frame 10 and the protrusion 82 located on the underside of
flexible seal member 60 contacts the inside surface of part 94 of frame trim 90.
The flexible seal member 60 may be fixed to window frame 10 or may simply be held
in position by frame trim 90 without the need for any additional fixing.
Operation of the above described sensing assembly will now be briefly described. In
the usual way, when the driver or passenger of the vehicle wishes to raise or lower a
window they operate a switch to energise a motor which drives the window up/down
in the window guide channel 12. The sensing assembly is used to detect a body part
which may have been placed in the gap between the window 8 and window opening
when the window is moving, and associated control circuitry will prevent further
upward movement of the window, thus avoiding the body part becoming trapped
between the window glass 8 and the window frame 10.
Control circuitry (not shown) is connected to the electrically conductive members 72
and 66 in said flexible seal member 60 and applies an electrically oscillating signal,
generated by a voltage controlled oscillator to the inner electrically conductive
member. This leads to an electric field being generated in the vicinity of the window
opening. Typical control circuitry is shown in EP 0648628B for example.
In a preferred embodiment of the invention the shape of the inner and outer electrically
conductive members is such that the generated electric field is concentrated in the
vicinity of the window opening. However the invention is not limited to electrically
conductive members having the specific shape herein described.
Once energised, the electrically conductive members 66 and 72 act as a capacitor
connected to the control circuitry. When a body part (or other object with a relatively
high dielectric constant) is within the vicinity of the electric field this will cause a
change in the capacitance of the capacitor formed by the electrically conductive
members 66 and 72. This change will be detected by the control circuitry and the
control circuitry will stop and/or reverse the motor controlling movement of the
window.
In figure 2, protrusion 82 is located on the underside of flexible seal member 66 in
contact with an inside surface of region 94 of frame trim 90. Any body part on the
rising edge of window glass 8 will (if movement of the window is not halted)
eventually contact region 94 of trim 90 as the window rises to the closed position.
Contact between a body part on the rising window edge and region 94 of trim 90 will
move the trim upwards toward the window frame 10. This movement will lead to
movement or deformation of the protrusion 82. The movement or deformation of the
protrusion 82 will subsequently cause flexible seal member 60 to be deformed and
inner electrically conductive portion 66 will be moved towards outer electrically
conductive member 72.
Movement of inner electrically conductive member 66 towards the outer electrically
conductive member 72 will cause a change in capacitance of the capacitor defined by
the two electrically conductive members 66 and 72 when they are energised as
described above. Like the non-contact detection mode previously described, this
change in capacitance will be detected by the control circuitry and will cause the motor
to be de-energised, thereby immediately stopping the rising window glass, and
preventing damage to the body part on the rising edge of the window.
It is also possible that movement of inner electrically conductive member 66 may be
so great, that it moves through the hollow chamber 70 and physically contacts the
outer electrically conductive member 72. In this case, there will be electrical contact
between the two electrically conductive members 66 and 72, and when they are
energised this will cause a short circuit. Once again, this interruption of the control
circuitry will cause the motor controlling the movement of window glass 8 to be de-
energised as described above, thereby immediately stopping the rising glass, if for
some reason it has not been stopped already.
Figure 3 shows an alternative embodiment of the invention to that shown in figure 2.
As can be seen, in this embodiment of the invention the flexible seal member 60 is
separate from, and does not contact, the window guide channel 12.
Elements of this figure which are the same as the corresponding elements of figure 2
will not be described, as the description provided for figure 2 applies equally here.
Like the embodiment in figure 2, frame trim 90 consists of consecutive regions 98, 96,
94 and 92. However, in this embodiment region 92 of frame trim 90 is received in
trim receiving channel 100 formed entirely within glass-receiving channel 12.
In the flexible seal member 60 of this embodiment part 86 of the body of flexible seal
member 60 is affixed to an inside surface of section 94 of frame trim 90 by adhesive
110, or similar bonding material. Other means of securing the flexible seal member 60
to the inside surface of frame trim 90 may also be used.
In this embodiment the protrusion 82 is on the opposite side of the flexible seal
member to the embodiment shown in figure 2, and is separated from outer electrically
conductive member 72 by sealing region 80. The protrusion contacts vehicle frame 10
at part 10C". Also in this embodiment the ends of side portions 76 of outer
electrically conductive member 72 define part of the perimeter of the hollow chamber
70.
The methods of operation of the sensing assembly showing in this figure are the same
as the methods of operation described for the assembly shown in figure 2.
