ABSTRACT:
A device for adjusting the inclined angle of the seating surface of the seat cushion of an automotive seat essentially mounted in a vehicle. A pair of seat slide adjusting units are fixed to seat slide upper rails arranged on a floor surface and are disposed at both sides of a seat cushion frame. A sector gear plate is so secured to a bracket fixedly secured to the seat slide adjusting unit as to be elevationally rocked at its base around a fulcrum. Another bracket is fixedly secured to the seat sliding adjusting unit. A pinion gear rotated by a handle knob is journaled at the another bracket at a fulcrum. The pinion gear is coupled through a non-reversing unit with the handle knob in a manner that the gear may be freely rotated by the operation of the knob but may not be rotated by the rotating load applied from the pinion gear side. The pinion gear is engaged in mesh with the teeth of the gear plate. A link is pivotally secured to a pin secured at the intermediate portion between the base and the teeth of the gear plate at the lower portion and is also pivotally secured at the axial hole of the upper portion thereof to the seat cushion frame. A bracket is also fixedly secured at the same situation as the previous bracket to the other seat slide adjusting unit. Thus, when the knob is manipulated, the seat cushion can be tilted up or down in response to the sitting person's physique or preference to his most comfortable attitude.
