Vehicle seat having combined contour and tilt adjustment

Claim 1

A vehicle seat assembly comprising: a base portion adapted to be secured to a supporting surface in fixed relationship with respect thereto; a seat mounted on said base portion; attachment means securing said seat to said base portion for fore and aft movement with respect thereto between an extreme rearward posItion and an extreme forward position in a path such that the seat tilts progressively forwardly as it moves forwardly from the extreme rearward position, said means including a fore and aft extending rail projecting upwardly from said base portion, a link pivotally connected between the seat portion of said seat and said rail, and means pivotally and slidably connecting the seat portion with said rail at a point spaced from said link; means for locking said seat relative to said base portion in a selected position with respect thereto; a pair of laterally spaced side members projecting forwardly from the forward edge of said seat; a rod connected to said side members; a leg rest member mounted on said side members for pivotal movement about a horizontal axis defined by the axis of said rod whereby the contour of said seat may be adjusted; and actuating means, attached to one of said side members, to cause rotation of said leg rest member about said rod and to prevent rotation in response to the application of pressure to said leg rest member said actuating means comprises a pivot arm and an actuating shaft rotatably mounted on one of said side members whereby rotation of said actuating shaft causes rotation of said pivot arm to rotate said leg rest member and whereby pressure on said leg rest member does not cause rotation of said pivot arm.
