Abstract
Abstract An improved latch arrangement for attaching the support bar of a headrest and an escutcheon to a vehicle seat back. A mounting bracket located on the seat back frame has vertically spaced apertures which slidably receive the support bar. An escutcheon conceals the opening in the top of the seat back and has a central aperture through which the support bar is inserted. A leaf spring is mounted on the mounting bracket and has first and second latch members mounted thereon. The first latch member and the escutcheon have coacting cam surfaces which deflect the spring to carry the first latch member out of the path of entry of the escutcheon. The escutcheon has an aperture into which the leaf spring biases the first latch member to attach the escutcheon to the seat back. The second latch member and the support bar have coacting cam surfaces which deflect the leaf spring and its second latch member to permit entry of the support bar. The support bar has an aperture into which the leaf spring biases the second latch member to attach the support bar to the seat back. A special tool is provided to facilitate removal of the support bar and escutcheon.

Claim 1
Independent Claim
201 words
In a vehicle seat including a seat back having an opening, a headrest cushion having a support bar, a mounting bracket within the seat back for slidably receiving the support bar, and an escutcheon for surrounding the support bar and trimming the opening in the seat back, the improvement comprising: spring biased means mounted on the seat back and having first and second latch members carried thereon, the first latch member and the escutcheon having coacting cam surfaces which are effective to deflect the spring biased means and carry the first latch member out of the path of entry of the escutcheon into the opening of the seat back, the escutcheon having an aperture therein into which the first latch member is engaged by the spring biased means to attach the escutcheon to the seat back, the second latch member and the support bar having coacting cam surfaces effective to deflect the spring biased means and carry the second latch member out of the path of entry of the support bar, and the support bar having an aperture thErein into which the second latch member is engaged by the spring biased means to attach the support bar to the seat back.

In a vehicle seat including a seat back having an opening, a headrest cushion having a support bar, a mounting bracket within the seat back for slidably receiving the support bar, and an escutcheon for surrounding the support bar and trimming the opening in the seat back, the improvement comprising: spring biased means mounted on the seat back and having first and second latch members carried thereon, the first latch member and the escutcheon having coacting cam surfaces which are effective to deflect the spring biased means and carry the first latch member out of the path of entry of the escutcheon into the opening of the seat back, the escutcheon having an aperture therein into which the first latch member is engaged by the spring biased means to attach the escutcheon to the seat back, the second latch member and the support bar having coacting cam surfaces effective to deflect the spring biased means and carry the second latch member out of the path of entry of the support bar, and the support bar having an aperture thErein into which the second latch member is engaged by the spring biased means to attach the support bar to the seat back.
Claim 3
Dependent Claim
254 words
In a vehicle seat including a seat back having an opening, a headrest cushion having a support bar, a mounting bracket within the seat back for slidably receiving the support bar, and an escutcheon for surrounding the support bar and trimming the opening in the seat back, the improvement comprising: spring biased means mounted on the seat back and having first and second latch members carried thereon, the first latch member and the escutcheon having coating cam surfaces which are effective to deflect the spring biased means and carry the first latch member out of the path of entry of the escutcheon into the opening of the seat back, the escutcheon having an aperture therein into which the first latch member is engaged by the spring biased means to attach the escutcheon to the seat back, the second latch member and the support bar having coacting cam surfaces effective to deflect the spring biased means and carry the second latch member out of the path of entry of the support bar, the support bar havng an aperture therein into which the second latch member is engaged by the spring biased means to attach the support bar to the seat back, and the interelationship between the respective latch members and cam surfaces being such as to maintain engagement of the first latch member in the aperture of the escutcheon when the spring biased means is deflected to the position in which the second latch member is not engaged in the aperture of the support bar.

In a vehicle seat including a seat back having an opening, a headrest cushion having a support bar, a mounting bracket within the seat back for slidably receiving the support bar, and an escutcheon for surrounding the support bar and trimming the opening in the seat back, the improvement comprising: spring biased means mounted on the seat back and having first and second latch members carried thereon, the first latch member and the escutcheon having coating cam surfaces which are effective to deflect the spring biased means and carry the first latch member out of the path of entry of the escutcheon into the opening of the seat back, the escutcheon having an aperture therein into which the first latch member is engaged by the spring biased means to attach the escutcheon to the seat back, the second latch member and the support bar having coacting cam surfaces effective to deflect the spring biased means and carry the second latch member out of the path of entry of the support bar, the support bar havng an aperture therein into which the second latch member is engaged by the spring biased means to attach the support bar to the seat back, and the interelationship between the respective latch members and cam surfaces being such as to maintain engagement of the first latch member in the aperture of the escutcheon when the spring biased means is deflected to the position in which the second latch member is not engaged in the aperture of the support bar.
Claim 5
Dependent Claim
218 words
In a vehicle seat including a seat back having an opening, a headrest cushion having a support bar, a mounting bracket within the seat back for slidably receiving the support bar, and an escutcheon for surrounding the support bar and trimming the opening in the seat back, the improvement comprising: a leaf spring mounted on the mounting bracket, a latch pin mounted on the leaf spring and extending into the path of entry of the support bar, a cam surface on the end of the support bar engaging the latch pin and deflecting the leaf spring to carry the latch pin out of the path of entry of the support bar, the leaf spring having a pair of latch members integral therewith and spaced laterally each side of the support bar, the upper end of the pair of latch members being inclined to provide cam surfaces located in the path of entry of the escutcheon into the seat back, the escutcheon engaging the cam surfaces to deflect the leaf spring and thereby carry the pair of latch members thereof out of the path of entry of the escutcheon, the escutcheon having slots therein aligned with the latch members and into which the latch members are biased by the leaf spring to latch the escutcheon on the seat back.
