Abstract
In a vehicle seat having a seat cushion subdivided, for set depth adjustment, into individual upholstery elements in the transverse direction of the seat, the individual upholstery elements are connected together by a coupling mechanism. The coupling mechanism is designed so that each of the gaps appearing between the upholstery elements when the depth is adjusted has the same gap width, and the upholstery elements, after conclusion of the set depth adjustment, are fixed in their particular adjusted position.
Claims12
Vehicle seat adjustable into a plurality of seat adjustment positions and having a back support and a seat cushion which is subdivided into a plurality of individual upholstery elements separated in a transverse direction of the seat;
- said upholstery elements each resting on rigid support means and being connected together and displaceably arranged relative to one another for seat depth adjustment by having ends of the rigid support means displaced in fixed guides extending in a longitudinal direction on both sides of the seat;
- coupling means for connecting said upholstery elements together such that a gap appears during seat depth adjustment between each said upholstery elements;
- wherein each said gap has an approximately eqaul width relative to the other said gaps for each said seat adjustment position and said upholstery elements are each fixed in a particularly adjusted position and wherein said coupling means causes displacement of the ends of said support means uniformly in said guide to separate said upholstery elements from one another.
Vehicle seat adjustable into a plurality of seat adjustment positions and having a back support and a seat cushion which is subdivided into a plurality of individual upholstery elements separated in a transverse direction of the seat;
- said upholstery elements being connected together and displaceably arranged relative to one another for seat depth adjustment in guides extending in a longitudinal direction of the seat;
- coupling means for coupling said upholstery elements such that a gap appears during seat depth adjustment between each said upholstery elements;
- each said gap having an approximately equal width relative to the other of said gaps for each said seat adjustment position;
- said upholstery elements each being fixed in a particularly adjusted position;
- stiff support elements with ends diplaceably located in guides;
- said coupling means having a trellis gear with trellis arms connected together via pin-joints;
- said pin-joints including central pin-joints fixed to at least one individual of said upholstery elements;
- said trellis arms having holes in their centers for receiving said central pin-joints;
- said pin-joints being formed by pins held on said support elements;
- two racks longitudinally displaceable in mutually opposite directions and motive means engaging with and displacing said racks, and wherein each of two of said trellis arms pin-joints connected to one another at their centers are, at their ends, pin-joint connected respectively to one of said racks.
