Abstract

Abstract A seat back angle adjuster and latch for a vehicle seat including a seat back having laterally spaced inboard and outboard support arms pivotally supporting the seat back for movement between use and easy enter positions. The seat back angle adjuster includes a two-position lever operated cam which is pivotally mounted on the seat frame and engages the inboard support arm to selectively define first and second angular use positions of the seat back relative the vertical. A seat back latch lever pivotally mounted on the outboard support arm has a pair of spaced recesses selectively engaging a pin extending from the seat frame to lock the seat back in either of the first or second use positions defined by the angle adjuster.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 194 words
A vehicle seat comprising a seat back having laterally spaced support arms, means pivotally attaching the support arms to the seat frame for permitting pivotal movement of the seat back between a plurality of angular use positions of the seat back relative the seat frame and a forwardly pivoted easy-enter position, an adjuster cam having a plurality of discrete cam surfaces, pivot means mounting the adjuster cam on the seat frame for movement to a position wherein a selected one of the plurality of discrete cam surfaces engages one of the support arms to define the angular use position of the seat back relative the seat frame, a latch lever having a plurality of spaced recesses therein, pivot means mounting the latch lever on the other of the support arms, means on the seat frame normally engaged in one of the plurality of spaced recesses of the latch lever to lock the seat back in the angle thereof defined by the selected one of the plurality of discrete cam surfaces, the latch lever being pivotable out of engagement with the seat frame means to permit pivotal movement of the seat back to easy-enter position.
Claim 2
Dependent Claim 194 words
A vehicle seat comprising a seat back having laterally spaced support arms, means pivotally attaching the support arms to the seat frame for permitting pivotal movement of the seat back between a plurality of angular use positions of the seat back relative the seat frame and a forwardly pivoted easy-enter position, an adjuster cam having a plurality of discrete cam surfaces, pivot means mounting the adjuster cam on the seat frame for movement to a position wherein a selected one of the plurality of discrete cam surfaces engages one of the support arms to define the angular use position of the seat back relative the seat frame, a latch lever having a plurality of spaced recesses therein, pivot means mounting the latch lever on the other of the support arms, means on the seat frame normally engaged in one of the plurality of spaced recesses of the latch lever to lock the seat back in the angle thereof defined by the selected one of the plurality of discrete cam surfaces, the latch lever being pivotable out of engagement with the seat frame means to permit pivotal movement of the seat back to easy-enter position.
Claim 3
Dependent Claim 229 words
A vehicle seat comprising a seat frame, a seat back having laterally spaced support arms, means pivotally attaching the support arms to the seat frame for pivotal movement of the seat back between use position and an easy-enter position forwardly of use position, adjuster cam means pivotally mounted on the frame and manually movable to first or second positions supportably engaging one of the support arms from rearward pivotal movement to define first and second angular use positions of the seat back relative the seat frame, a latch lever pivotally mounted on the other support arm and having first and second recesses therein, means on the seat frame engageable within the first or second recesses of the latch lever, spring means biasing the latch lever into engagement with the means on the seat frame to lock the seat back in the respective angular use position thereof defined by the adjuster cam means, a handle on the latch lever permitting rotation of the latch lever and disengagement from the means on the seat frame to permit forward pivotal movement of the seat back to the easy-enter position, and cam surfaces on the latch lever rearwardly the first and second recesses engaging the means on the seat frame to rotate the latch lever against the bias of the spring during rearward pivotal movement of the seat back from the easy-enter position.
Claim 4
Dependent Claim 229 words
A vehicle seat comprising a seat frame, a seat back having laterally spaced support arms, means pivotally attaching the support arms to the seat frame for pivotal movement of the seat back between use position and an easy-enter position forwardly of use position, adjuster cam means pivotally mounted on the frame and manually movable to first or second positions supportably engaging one of the support arms from rearward pivotal movement to define first and second angular use positions of the seat back relative the seat frame, a latch lever pivotally mounted on the other support arm and having first and second recesses therein, means on the seat frame engageable within the first or second recesses of the latch lever, spring means biasing the latch lever into engagement with the means on the seat frame to lock the seat back in the respective angular use position thereof defined by the adjuster cam means, a handle on the latch lever permitting rotation of the latch lever and disengagement from the means on the seat frame to permit forward pivotal movement of the seat back to the easy-enter position, and cam surfaces on the latch lever rearwardly the first and second recesses engaging the means on the seat frame to rotate the latch lever against the bias of the spring during rearward pivotal movement of the seat back from the easy-enter position.
