Abstract
Abstract The seat cushion of a bench type vehicle seat has a first end pivotally mounted on the vehicle body and a second end mounted by a track assembly permitting fore and aft sliding movement of the second end so that the entire seat swivels about the first end. A link is located adjacent the second end of the seat cushion and has a lower end pivoted to the vehicle floor. A seat back has one end pivotally connected to the first end of the seat cushion and another end pivotally connected to the link. The link has a cam slot in which a cam roller mounted on the seat cushion is slidably engaged so that pivotal movement of the link effects fore and aft sliding movement of the second end of the seat cushion. A first latch is provided between the link and the seat. A second latch is provided between the seat back and the vehicle body. When the second latch is released the seat back and link are permitted to pivot forwardly which in turn induces forward swiveling movement of the seat cushion to facilitate access behind the seat. A lost motion connecting linkage is provided between the first and second latches so that unlatching of the first latch effects simultaneous unlatching of the second latch to permit pivotal movement of the seat back relative the seat cushion and the link to thereby move the seat back to a cargo floor forming position overlying the seat cushion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
257 words
A seat for a motor vehicle comprising: a seat cushion, means pivotally mounting a first end of the seat cushion on the motor vehicle, track means mounting a second end of the seat cushion on the motor vehicle to permit fore and aft sliding movement of the second end of the seat cushion between a normal rearward position and a forward position facilitating access behind the seat cushion, a seat back, a link located adjacent the second end of the seat cushion, pivot means connecting one end of the link to the vehicle body, seat back pivot means pivotally connecting a first end of the seat back to the first end of the seat cushion and pivotally connecting a second end of the seat back to the other end of the link to permit the seat back to be folded downwardly to a cargo floor forming position overlying the seat cushion, latch means acting between the link and the seat back to prevent pivotal movement of the seat back relative the link when the latch means is engaged to thereby prevent forward folding movement of the seat back to the cargo floor forming position, and means acting between the seat cushion and the link whereby when the latch means is latched, and forward pivoting movement of the seat back pivots the link, the seat cushion is moved forwardly to the forward position as permitted by pivoting of the one end of the seat by the associated pivot means and by the sliding movement of the track means.
Claim 2
Dependent Claim
257 words
A seat for a motor vehicle comprising: a seat cushion, means pivotally mounting a first end of the seat cushion on the motor vehicle, track means mounting a second end of the seat cushion on the motor vehicle to permit fore and aft sliding movement of the second end of the seat cushion between a normal rearward position and a forward position facilitating access behind the seat cushion, a seat back, a link located adjacent the second end of the seat cushion, pivot means connecting one end of the link to the vehicle body, seat back pivot means pivotally connecting a first end of the seat back to the first end of the seat cushion and pivotally connecting a second end of the seat back to the other end of the link to permit the seat back to be folded downwardly to a cargo floor forming position overlying the seat cushion, latch means acting between the link and the seat back to prevent pivotal movement of the seat back relative the link when the latch means is engaged to thereby prevent forward folding movement of the seat back to the cargo floor forming position, and means acting between the seat cushion and the link whereby when the latch means is latched, and forward pivoting movement of the seat back pivots the link, the seat cushion is moved forwardly to the forward position as permitted by pivoting of the one end of the seat by the associated pivot means and by the sliding movement of the track means.
Claim 3
Dependent Claim
279 words
A seat for a motor vehicle comprising: a seat cushion, means pivotally mounting one end of the seat cushion on the motor vehicle; track means mounting the other end of the seat cushion on the motor vehicle and permitting fore and aft sliding movement of the seat cushion between a normal rearward position and a forward position facilitating access behind the seat cushion; a seat back; means pivotally connecting one end of the seat back to the seat cushion; a link located adjacent the other end of the seat back and having a cam slot therein; first pivot means connecting one end of the link to the vehicle body and second pivot means connecting the other end of the link to the seat back; first latch means acting between the link and the seat back to prevent pivotal movement of the seat back about the second pivot means when the first latch means is latched; second latch means acting between the seat back and the vehicle body to retain the seat back in a normal upright seat forming position when latched; and cam follower means on the seat cushion slidably engaged in the cam slot of the link whereby when the second latch means is unlatched and the first latch means is latched, forward pivoting movement of the seat back pivots the link and the cam follower means rides in the cam slot to move the vehicle seat cushion forwardly to the forward position, simultaneous unlatching of the first and second latch means permitting the seat back to pivot relative the link so that the seat back is folded downwardly to cargo floor forming position overlying the seat cushion.
Claim 4
