Seat position control mechanism

Claim 2

In a vehicle seat including a seat back movable from an upright position rearwardly to a plurality of inclined positions or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and from any adjusted position to an easy enter position, a seat position control mechanism comprising, actuating means operable by tilting movement of the seat back to displacement the seat from any one of the adjusted positions to the easy enter position, means blocking operative connection of the actuating means to the seat back when the seat back is in the upright position and in any of the inclined positions, and means operated by forward movement of the seat back toward tilted position for operatively connecting the seat back to the actuating means.

Claim 3

In a vehicle seat including a seat back movable rearwardly from an upright position to an inclined position or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and an easy enter position, and means releasably locking the seat in any one of the adjusted positions, a seat position control mechanism comprising, actuating means operable by tilting movement of the seat back to displace the seat from any one of the adjusted positions to the easy enter position, means blocking operative connection of the actuating means to the seat back when the seat back is in the upright position and inclined position, means operated by forward movement of the seat back toward tilted position for operatively connecting the seat back to the actuating means, and means releasing the locking means upon establishment of an operative connection of the actuating means to the seat back to permit movement of the seat to the easy enter position.

Claim 4

In a vehicle seat including a seat back movable rearwardly from an upright position to an inclined position or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and an easy enter position, and means releasably locking the seat in any one of the adjusted positions, a seat position control mechanism comprising, actuating means operable by tilting movement of the seat back to displace the seat from any one of the adjusted positions to the easy enter position, means blocking operative connection of the actuating means to the seat back when the seat back is in the upright position and inclined position, means operated by forward movement of the seat back toward tilted position for operatively connecting the seat back to the actuating means, and means releasing the locking means upon establishment of an operative connection of the actuating means to the seat back to permit movement of the seat to the easy enter position.

Claim 5

In a vehicle seat including a seat back movable rearwardly from an upright position to a plurality of inclined positions or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and an easy enter position, a seat position control mechanism comprising, an actuating member pivoted to the seat and pivotally and slidably connectable to the vehicle to displace the seat from any one of the adjusted positions to the easy enter position upon movement thereof relative to the seat and vehicle, a seat back mounted member freely pivotally connected to the actuating member, interengageable pawl and ratchet means for releasably securing the seat back mounted member to the actuating member to move the actuating member relative to the seat and vehicle upon tilting movement of the seat back and thereby displace the seat from an adjusted position to the easy enter position, and means blocking engagement of the pawl and ratchet means when the seat back is in the upright position or in any of the inclined positions.

Claim 6

In a vehicle seat including a seat back movable rearwardly from an upright position to a plurality of inclined positions or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and an easy enter position, a seat position control mechanism comprising, an actuating member pivoted to the seat and pivotally and slidably connectable to the vehicle to displace the seat from any one of the adjusted positions to the easy enter position upon movement thereof relative to the seat and vehicle, a seat back mounted member freely pivotally connected to the actuating member, interengageable pawl and ratchet means for releasably securing the seat back mounted member to the actuating member to move the actuating member relative to the seat and vehicle upon tilting movement of the seat back and thereby displace the seat from an adjusted position to the easy enter position, and means blocking engagement of the pawl and ratchet means when the seat back is in the upright position or in any of the inclined positions.

Claim 7

In a vehicle seat including a seat back movable from an upright position rearwardly to a plurality of inclined positions or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and from any adjusted position to an easy enter position and return to the adjusted position, a seat position control mechanism comprising, actuating means operable by movement of the seat back forwardly from the upright position to a tilted position to displace the seat from an initial adjusted position to the easy enter position and operable by return of the seat back from the tilted position to upright position to return the seat to the initial adjusted position, means normally disconnecting the actuating means from the seat back to permit rearward movement of the seat back between the upright and inclined positions, and means operated by forward movement of the seat back from upright to tilted position for operatively connecting the seat back to the actuating means to displace the seat to the easy enter position, movement of the seat back from the tilted position to the upright position disconnecting the seat back from the actuating means when the seat returns to the initial adjusted position.

Claim 8

In a vehicle seat including a seat back movable from an upright position rearwardly to a plurality of inclined positions or forwardly to a tilted position, means for mounting the seat on a vehicle for movement to a plurality of adjusted positions and from any adjusted position to an easy enter position and return to the adjusted position, a seat position control mechanism comprising, actuating means operable by movement of the seat back forwardly from the upright position to a tilted position to displace the seat from an initial adjusted position to the easy enter position and operable by return of the seat back from the tilted position to upright position to return the seat to the initial adjusted position, means normally disconnecting the actuating means from the seat back to permit rearward movement of the seat back between the upright and inclined positions, and means operated by forward movement of the seat back from upright to tilted position for operatively connecting the seat back to the actuating means to displace the seat to the easy enter position, movement of the seat back from the tilted position to the upright position disconnecting the seat back from the actuating means when the seat returns to the initial adjusted position.
