DEVICE TO ADJUST RELATIVE POSITION OF BACKREST AND CUSHION OF VEHICLE SEAT Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: proposed device has movable bracket supported by fixed bracket by means of axle and providing possibility of rotation of one bracket relative to the other, and lock mechanism. Said mechanism is made in form of newly introduced tie-rod hinge mounted to form power arm relative to axle and located in hinge joint installed in fixed bracket for adjusting its travel in cross direction relative to axle. Tie-rod can be made in form of lead screw, rack with grooves, rod of hydro- or pneumocylinder with piston. Cylinder space is divided into two chambers interconnected by channel accommodating shutoff device, for instance, plug cock. Invention provides automation of control of working member drive owing to possibility of use of vehicle storage battery or its pneumatic or hydraulic systems. EFFECT: simplified design, reduced labor input in manufacture. 7 cl, 6 dwg
