VEHICLE SEAT SIDE TILTING ADJUSTER Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to vehicle seats with adjustable elements and it can be used in tractors operating on slopes. According to invention, device has upper and lower supports, each coupled, respectively, with frame and cushion of seat and is furnished with two guide members with travel limiters and controllable spring-loaded stop secured on upper support. Arc-shaped guide members of upper support are installed on brackets for angular displacement in plane square to longitudinal axis of seat, and one of guide members of upper support is provided with radial slot for engagement with stop. Lower support is furnished with brackets located in plane of displacement of arc-shaped guides and is connected in pairs by plates, one of which has radial slots in zone of longitudinal axis of seat for engagement with stop. Guide members of lower support are made in form of balls arranged in base of each bracket to adjoin arc-shaped guide members of upper support under action of pressure mechanism. Arc-shaped members travel limiters are made in form of bent ends of their brackets. Stop is made in form of plate secured on axle of bracket of upper support for engagement with radial slot of arcshaped member through set radial slot of lower support plate. Pressure mechanism can be made in form of eccentric washer with adjusting screw or in form of wire spring with bent off V-shaped ends. EFFECT: provision of quick action and easy change-over owing to use of rolling friction guide members instead of sliding friction ones, reduced materials usage. 5 cl, 7 dwg
