Abstract
Description
- The present invention is generally directed to a mounting anchor and, more specifically, a mounting anchor for a motor vehicle.
- Traditionally, motor vehicle manufacturers have designed cars to meet many different safety standards and regulations, which have been implemented to protect adult occupants. As such, car seat cushions, seat belt design and anchorage locations have all been optimized for the comfort and protection of adults. Unfortunately, motor vehicle design has not traditionally taken into account that child restraints may need to be attached to one or more of the components of a motor vehicle. In 1990, a standard system known as ISOFIX was proposed for attaching child restraints in motor vehicles in a manner that reduced the risk of injury to a child in the event of a collision.
- Broadly, the goals of ISOFIX are to provide a standard universal means of attaching child restraints, eliminate improper installation of child restraints in motor vehicles, improve dynamic performance of child restraints and ensure a more consistent dynamic performance of child restraints. However, while ISOFIX mounting anchors are becoming more common in the front passenger seat of motor vehicles sold in North America, existing ISOFIX mounting anchors do not allow for the detection of a child seat.
- What is needed is a mounting anchor that allows for the detection of a child seat. It would also be desirable if the mounting anchor provided for differentiating between rearward facing infant seats, forward facing infant seats and a booster seat or car bed.
- A mounting anchor for a motor vehicle includes a locking bar, a first switch, a first movable plate, a second switch and a second movable plate. A portion of the locking bar is shaped to receive a mateable connector and an interior of at least portions of first and second sides of the locking bar include grooves. The first switch is positioned adjacent the first side of the locking bar and the first movable plate is positioned to slidably engage the groove on the first side of the locking bar. The first movable plate includes a first activation area for receiving a portion of the first switch and a first aperture for receiving a first rotatable arm. The second switch is positioned adjacent the second side of the locking bar, which is opposite the first side of the locking bar. The second movable plate is positioned to slidably engage the groove on the second side of the locking bar and includes a second activation area for receiving a portion of the second switch and a second aperture for receiving a second rotatable arm. The mateable connector includes at least one of the first and second rotatable arms, which, when received in an associated one of the first and second apertures, initiates movement of an associated one of the first and second movable plates and activation of at least one of the first and second switches.
- According to another embodiment of the present invention, the locking bar is shaped to engage a releasable lock for receiving and retaining the locking bar with the releasable lock being included within the mateable connector. According to a further embodiment of the present invention, the lock includes a pair of locking jaws, each shaped to engage the locking bar. The mateable connector may be attached to one of a front of an infant seat, a rear of an infant seat, a booster seat and a car seat. According to a further embodiment of the present invention, the mounting anchor includes a spring for biasing the first and second movable plates toward a front of the locking bar. According to an additional aspect of the present invention, the spring includes separate springs for individually biasing the first and second movable plates.
- According to a different aspect of the present invention, the first and second movable plates are slidably engaged and, according to yet another embodiment of the present invention, the first and second movable plates are coplanar.
- These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.
- The present invention will now be described, by way of example, with reference to the accompanying drawings, in which:

FIGS. 11-13 are electrical schematics of electrical interface circuits that may be utilized to electrically couple first and second switches associated with the mounting anchor to an electronic control unit for determination of whether the first and second switches are activated. - According to the present invention, a mounting anchor is disclosed herein that includes two movable switches that provide three distinct electromechanical states such that rearward facing child seats, forward facing child seats and a booster seat or car bed can be distinguished from one another such that motor vehicle subsystems can take appropriate action based thereon. For example, a motor vehicle subsystem may deactivate a passenger-side airbag and/or provide a warning that a rearward facing child seat should not be placed in the front of the motor vehicle when the child seat is attached to a mounting anchor associated with a front passenger-side seat. As is disclosed herein, a number of different alternative electrical circuits may be used to interface with two movable switches such that an electronic control unit can readily determine the presence/absence of a child seat and specifically identify any child seat that is present and/or detect an improperly installed seat and issue a warning.

With reference toFIG. 11 , a Hall-effect type interface 300 is shown. Theinterface 300 ofFIG. 11 is a two wire interface defined by the following equations:
I 0 =V+/((R1*R2)/(R1+R2)+R5)
I 1 =V+/(((R1*R2)/(R1+R2)*R3)/(R1*R2)/(R1+R2)+R3))+R5)
I 2 =V+/(((R1*R2)/(R1+R2)*R4)/(R1*R2)/(R1+R2)+R4))+R5)
I 3 =V+/(((R1*R3)/(R1+R3)*(R2*R4)/(R2+R4)/((R1*R3)/(R1+R3)+(R2*R4)/(R2+R4))+R5)
where I0 is the state where neither switch S1 nor switch S2 are closed, I1 is the state where switch S1 is closed, I2 is the state where switch S2 is closed and I3 is the state where both switches S1 and S2 are closed. Depending on individual application requirements, care should be taken in selecting component values to assure sufficient differentiation between current levels. - With reference to
FIG. 12 , anotherexemplary interface 302 is shown. The equations for theinterface 302 are set forth below:
V 0 =V + *R5/((R1*R2)/(R1+R2)+R5)
V 1 =V + *R5/(((R1*R2)/(R1+R2)*R3)/(R1*R2)/(R1+R2)+R3))+R5)
V 2 =V + *R5/(((R1*R2)/(R1+R2)*R4)/(R1*R2)/(R1+R2)+R4))+R5)
V 3 =V + *R5/(((R1*R3)/(R1+R3)*(R2*R4)/(R2+R4)/(R1*R3)/(R1+R3)+(R2*R4)/(R2+R4)+R5)
where V0 is the state where neither switch SW1 nor switch SW2 are closed, V1 is the state where switch SW1 is closed, V2 is the state where switch SW2 is closed and V3 is the state where both switches SW1 and SW2 are closed. Theinterface 302 provides voltage differentiation between the possible levels. However, theinterface 302 is a three wire interface and may be more susceptible to coupled noise, partial opens and partial shorts. - With reference to
FIG. 13 , anotheranalog voltage interface 304 is shown that provides greater differentiation between levels than theinterface 302 ofFIG. 12 . In its current state, theinterface 304 cannot differentiate an open pin from state 0, cannot differentiate a short to ground on a return from state 2 and cannot differentiate a short to battery on a return from state 1. The equations which define theinterface 304 are shown below:
V0=Float
V1=V+
V2=Ground
V 3 =V + *R2/(R1+R2) - Accordingly, a number of electrical interface circuits have been described herein that may be utilized in a mounting anchor system designed according to the present invention. It should be appreciated that the electrical interface circuit utilized in a mounting anchor system designed according to the present invention is not critical and a wide variety of electrical interface circuits may be utilized. The electrical interface circuits shown in
FIGS. 11-13 have been provided for reference only. - The above description is considered that of the preferred embodiments only. Modifications of the invention will occur to those skilled in the art and to those who make or use the invention. Therefore, it is understood that the embodiments shown in the drawings and described above are merely for illustrative purposes and not intended to limit the scope of the invention, which is defined by the following claims as interpreted according to the principles of patent law, including the doctrine of equivalents.
