Abstract
The present invention involves a pelvis activated vehicle seat and headrest assembly for rear impact of a vehicle. The vehicle seat includes a seatback frame and the headrest assembly includes a pelvis activated support assembly attached to the seatback frame. The seatback frame includes an upper cross member having two side members integrally and oppositely attached on either end of the upper cross member. The side members extend downwardly and are attached to each other by a lower cross member. The support assembly includes a reaction plate and an impact target. The impact target is pivotably attached proximate the bottom portion of the seatback frame. The reaction plate is pivotally attached to each side member by pivoting side links. The impact target is slidably connected to the reaction plate to move the headrest cushion to an actuated position forward and above a normal position.
Description
- This application is a continuation of U.S. application Ser. No. 10/079,756, filed Feb. 19, 2002, which in turn, claims the benefit of U.S. provisional application Serial No. 60/269,923 filed Feb. 19, 2001.
- 1. Field of the Invention
- The invention relates to a system for moving a headrest assembly of a vehicle seat upward and forward in the event of a rear impact.
- 2. Background Art
- Improvements in safety mechanisms in the automotive industry continue to be made year after year. One example of such a safety mechanism includes a safety headrest as disclosed in U.S. Pat. No. 5,378,043. Headrests are provided to support the head of an occupant during a collision.
- In a rear impact, a vehicle seat occupant may be driven rearwardly to exert a reaction force on the vehicle seat back. The pelvis and buttocks region of an occupant generally exerts more force initially on the seat back than the shoulder region of the occupant. This initial load applied by the pelvis and buttocks of the occupant may cause the seat back to be deflected rearwardly. As the seat back moves rearwardly, separation between the seat back and an occupant's head and torso may be increased.
- In an attempt to solve this problem, active headrest mechanisms have been proposed in which the occupant's torso applies a rearward load or force to an impact target in the vehicle seat. The impact target is connected to a headrest cushion portion that moves forward upon application of a rearward load on the impact target. The cushion portion moves forward toward the head of the occupant to lessen the gap between the head of an occupant and the headrest cushion portion in a collision.
- According to one aspect of the present invention, an improved vehicle seat and active headrest assembly combination is provided. The active headrest is activated by the application of a rearward pelvic load or force to the lower portion of a seat back by an occupant in a rear impact. The assembly includes a seatback frame and a dynamic headrest assembly support that moves the headrest in an upward and forward direction. The headrest assembly support includes a pivotal lower target that is oriented to be contacted by a seat occupant's pelvic region and a reaction plate to which the headrest assembly is secured that pivots and moves upwardly when the lower target is contacted.
- The reaction plate is slidably attached to the upper end of the lower target and is attached to the sides of the seat back frame by pivoting links. Apertures formed on the reaction plate are aligned with holes formed on an upper cross member of the seat back frame. The apertures receive bushings that slidably receive a pair of headrest posts of the headrest assembly. The headrest posts extend through the holes in the upper cross member of the seat back frame and apertures in the reaction plate.
- The headrest assembly is retained in a normal position generally in line with the seat back. Upon rear impact of the vehicle, the cushion portion of the headrest assembly is moved toward the head of the occupant to an actuated position that is raised and forward of the normal position to provide additional support to the head of the occupant sooner than if the headrest assembly were to remain fixed relative to the seat back. The cushion portion of the headrest assembly is moved toward the head of the occupant in response to the application of a rearward load by an occupant's pelvis on the lower target. As the upper portion of the lower target pivots rearwardly it applies a force to a lower portion of the reaction plate below a pivot axis of the linkage that connects the reaction plate to the seatback. The lower portion of the reaction plate shifts backwardly and upwardly. The upper portion of the reaction plate moves forwardly and upward carrying with it the headrest cushion.
- FIG. 1 is a side view depicting an operation of a headrest assembly in accordance with the present invention;
- FIG. 2 is front view of a headrest assembly in accordance with the present invention; and
- FIG. 3 is a fragmentary perspective view illustrating the headrest assembly, lower target and reaction plate attached to a seatback frame.
- Referring now to FIG. 1, a
vehicle seat 9 is shown in combination with aheadrest assembly 10. Acushion portion 11 ofassembly 10 is retained in anormal position 13 a generally aligned with the seat back during normal vehicle operation. It should be understood that the headrest may be adjusted manually within a range of positions in accordance with the invention. Upon rear impact of the vehicle, thecushion portion 11 of theheadrest assembly 10 moves to an actuatedposition 13 b potentially providing support to the head of the occupant. - Referring now to FIG. 2, a
seat back frame 12 and pivotal support assembly generally referred to byreference numeral 14 are illustrated wherein the pivotal support assembly is movably attached to theseat back frame 12.Seatback frame 12 includesupper cross member 20 that has a plurality ofholes 22 in which the headrest assembly is received. The upper cross member extends between twoends Seatback frame 12 further includesside members upper cross member 20 and extend generally downwardly from theends upper cross member 20, respectively, and are connected on the lower ends tolower cross member 34.Lower cross member 34 may be attached to theside members - Referring now to FIGS. 2 and 3, the
pivotal support assembly 14 includes lower target orimpact target 40 andreaction plate 52 that is slidably attached to theimpact target 40.Impact target 40 includes alower end 42 and anupper end 44.Lower end 42 is pivotally attached to the top oflower cross member 34 at substantially the center thereof, such thatimpact target 40 may pivot about first pivot axis A. When a rearward force or load is directed toward thelower end 42, vertical impact target 40 pivots backwardly. More specifically, the rearward force may be directed to an area onvertical impact target 40 which encompasseslower end 42. However, the rearward force may also include an area on theimpact target 40 abovelower end 42 that will cause pivotal movement ofimpact target 40.Lower end 42 is pivotally attached to the top oflower cross member 34 by any suitable means to allow pivoting about first pivot axis A. As shown in FIG. 3, for example,bearings 38 may be disposed at the top oflower cross member 34 to receive abar 36 that is secured to thelower end 42. In the illustrated embodiment, thelower end 42 pivots about the first axis A approximately 5-7 degrees but other ranges of motion could be provided depending upon design constraints. - Referring now to FIGS. 2 and 3, the
impact target 40 further includesslot 46 near its upper end through which alatch 50 ofreaction plate 52 is inserted to slidably attachreaction plate 52 tovertical impact target 40. Each of the right and left sides ofreaction plate 52 includes aside link 56. Eachside link 56 is pivotally attached to one of theside members B. Side links 56 swing about pivot axis B to allowreaction plate 52 to pivot and move upwardly.Latch 50 inserts intoslot 46 to allow upward sliding motion ofreaction plate 52 relative tovertical impact target 40 aslower end 42 pivots about first pivot axis A. Thus, as vertical impact target 40 pivots about axis A,side links 56 pivot about axis B to allowreaction plate 52 to slide upwardly with the portion of the reaction plate below pivot axis B shifting rearwardly. A locking mechanism (not shown) may be incorporated to fix or lock theimpact target 40 in an actuated position when target 40 pivots about first pivot axis A. The locking mechanism may comprise a conventional ratchet mechanism locatedadjacent headrest posts 57,bushings 60, orlatch 50. - It should be understood that the length of the
impact target 40 betweenlower end 42 andupper end 44 may vary. It has been found that as the distance between first pivot axis A and second pivot axis B increases, the corresponding movement ofheadrest frame 62 andcushion portion 11 will also increase. - Referring to FIGS. 2 and 3, the
reaction plate 52 includesapertures 54 that are in alignment with theholes 22 in theupper cross member 20. In this embodiment,bushings 57 are disposed withinapertures 54 to receiveheadrest post 60 ofheadrest frame 62.Bushings 57 are press fit or otherwise secured within the ofapertures 54.Bushings 57 receiveheadrest posts 60 in a sliding relationship to facilitate adjusting the height of the headrest in its normal position. Eachheadrest post 60 is inserted through one of theholes 22 in theupper cross member 20 and is received in one of thebushings 57. - In the event of a relatively severe rear impact to a vehicle in which the
vehicle seat 9 is disposed, the occupant's pelvis applies a rearward load ontolower end 42 of theimpact target 40 causing it to pivot rearwardly about first pivot axis A. The pivotal movement of theimpact target 40 causesreaction plate 52 to slide rearwardly and upwardly. More specifically, as theimpact target 40 pivots about first axis A,latch 50 ofreaction plate 52 slides upwardly alongslot 46 of theimpact target 40 andreaction plate 50 swings about second axis B on the side links 56. This is possible because side links 56 allowreaction plate 52 to pivot in the opposite direction to the direction of theimpact target 40 and move upwardly asvertical impact target 40 applies a rearward load on the lower portion of the reaction plate. The movement ofreaction plate 52, in turn, allowsheadrest frame 62 to be moved in an upward and forward direction. - In normal vehicle seat and headrest assemblies, during the initial stages of a rear impact, the occupant's torso is in contact with the seatback but the head is several inches forward of the cushion portion. This condition is consistent with the body being reclined at about 20° from vertical with the neck being approximately vertical. The head is usually not in contact with the cushion portion while driving. Depending upon the compliance of the seatback, the pelvic region or buttocks of a seat occupant compress into the cushion, while the head, neck, and torso move in unison. Typically, there is a greater compression in the buttocks region of the seat occupant, with a gradual reduction up to the shoulder level as the body remains upright. The more severe the crash, the greater the extent of the compression of the occupant into the seat. As this action is occurring, the initial load of the occupant may cause the seat to deflect rearwardly. The amount of deflection is related to the bending stiffness of the seat back. The seat back may deflect under the torso load prior to the time that the head and neck of the occupant contacts the cushion portion. In a conventional seat, a gap may develop between the head and the cushion portion in a rear impact collision.
- In the present invention, the force of the occupant's pelvis against the
impact target 40 causes the headrest assembly to move toward the vehicle occupant's head to minimize the gap between the occupant's head and thecushion portion 11. The greater the rear crash acceleration, the greater the resultant force exerted by the seat occupant, and the greater the forward movement of thecushion portion 11 toward the occupant's head. - As stated above, prior headrest assemblies are typically activated by contact with the upper torso or shoulder area of an occupant. We have found that locating an impact target of a headrest assembly near the pelvis of an occupant provides improved results. For example, it has been found that locating the impact target of the assembly adjacent the pelvis provides an earlier movement of the headrest towards the head of the occupant upon rear impact. Moreover, it has been found that greater distance of movement of the headrest results when the impact target is located near the pelvis rather than near the upper torso or shoulders of the occupant. In addition, it has been found that locating the impact target near the pelvis increases the force with which the headrest moves towards the head of the occupant. This results in improved support for the head of the occupant.
- As depicted in FIG. 1, operation of the
headrest assembly 10 provides a distance of movement of the cushion portion from a normal position to an actuated position. The distance has been found to be greater than the distance of movement of a typical headrest assembly having an impact target activated by the shoulder region of an occupant. In the present invention, results have shown that the distance traveled by the pelvis compared to the distance moved by the headrest cushion may be at a ratio of 1:3 to a ratio of 1:5. The transmission ratio may be adjusted simply by adjusting the length of the lower target and/or the distance between the first pivot axis A and the area where the reaction plate slides on the vertical impact target. The resulting force placed upon the headrest will vary depending on the force applied to the lower end of the impact target. - While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
