The present disclosure provides a pumping device of a vehicle seat and its operation mechanism. The pumping device includes: a housing encasing a pumping mechanism; a spring guide which has a ring shape formed with a cavity and is seated on a top surface of the housing, a coil spring being inserted in the spring guide; and a lever bracket which has a protruding portion formed on a central portion, an operating lever being coupled to a flange, and a locking protrusion protruding from the flange and locked to the coil spring through the guide slit of the spring guide. In particular, the protruding portion is connected to a cam of the pumping mechanism in a state of being inserted into the cavity of the spring guide

A system for adjusting the position of an automotive seat is described, comprising storage in memory of at least one predetermined position of the seat associated with a predefined driving condition, devices for monitoring the dynamics of the vehicle, and a control system of actuating devices for the movement of the seat, or at least a part thereof. The control system is arranged to identify a driving condition of the vehicle on the basis of the dynamics thereof, to select a seat position predetermined according to the driving condition, and to control the movement of the seat or at least a part thereof in such a way as to obtain the selected seat position.

A seat cushion device capable of adjusting hardness of a seat cushion including a seating surface, on which a user is seated, includes a recessed part that is formed in a back surface of the seating surface in the seat cushion, a left plate that faces a back surface of a left thigh holding part of the seating surface, on which a left leg thigh of the user is located, and that is movable inside the recessed part vertically, a right plate that faces a back surface of a right thigh holding part of the seating surface, on which a right leg thigh of the user is located, and that is movable inside the recessed part vertically, and a gap adjustment mechanism that moves the left plate and the right plate vertically in an independent manner, and that can adjust a clearance from the back surface of the seating surface.

A vehicle seat assembly is provided and includes a base assembly, a seat frame assembly attached to the base assembly, and a seat tilt control mechanism attached to the base assembly and the seat frame assembly. Actuation of the tilt drive assembly adjusts a tilt position of the seat frame assembly with respect to the base assembly.

A method for the automatic adjustment of a cockpit inside a road vehicle comprising the steps of determining anthropometric data of a driver; processing an ergonomic position of a model of the driver sitting on board the road vehicle; processing an optimal configuration of the cockpit; operating a plurality of actuator systems so as to cause the cockpit to reach the optimal configuration; wherein the ergonomic position of the model is processed in association with a minimum ground visibility; a minimum visibility of a control panel; and at least one first comfort angle of a body joint of the driver.

A seat-interlocking leg rest control system includes: a first actuator configured to move a seat for a vehicle, the seat including a seat cushion and a seatback, in a forward-backward direction or an upward-downward direction of the vehicle; a second actuator configured to rotate a leg rest, rotatably coupled to the front end portion of the seat cushion, in the upward-downward direction; and a controller connected to the first actuator and the second actuator to control operation of the second actuator such that the rotation angle of the leg rest is limited based on the position of the seat.

Systems, methods, and apparatuses related to an adjustable seating assembly for a golf cart are described. The golf cart includes a chassis, a prime mover, a plurality of tractive elements, at least one of the plurality of tractive elements driven by the prime mover, and a seating assembly supported by the chassis. The seating assembly includes a pedestal coupled to the chassis, a base support coupled to the pedestal, and a seat coupled to the base support. a track positioned to facilitate translationally repositioning at least one of the seat or the base support. The seating assembly includes a back support pivotably coupled to the base support or the pedestal and a back rest coupled to the back support. The seating assembly includes a first actuator configured to translate the at least one of the seat or the base support, and a second actuator configured to pivot the back support.
