Actuation of the tilt drive assembly adjusts a tilt position of the seat frame assembly with respect to the base assembly.

Disclosed is a low-posture zero-gravity seat frame capable of being adjusted in multiple directions. A first left front connecting rod has a lower end hinged to a left slide rail front bracket and an upper end hinged to one end of a second left front connecting rod, and the other end of the second left front connecting rod is hinged to a front horizontal tube. A second toothed plate driving device is able to adjust the height of a seat framework through the movement of a rear horizontal tube. A seatbelt retractor is disposed below the seat framework. The seat frame can realize zero-gravity adjustment, occupies a small space, and can fulfill low-posture seat arrangement.

An automobile seat integrated with height adjustment and angle adjustment comprises a seat body comprising a pedestal skeleton and a backrest skeleton, a height adjustment mechanism comprising a bottom support, a rear connection rod, an upper connection rod and a front connection rod and an angle adjustment mechanism comprising the bottom support, an angle adjustment connection rod, a driving connection rod, a front connection rod and the upper connection rod, the bottom support, the front connection rod and the upper connection rod are common parts of the height adjustment mechanism and the angle adjustment mechanism, the bottom support, the rear connection rod, the upper connection rod and the front connection rod are successively adjacently connected by rotating pairs, and the rear connection rod is connected with a height adjustment driving source which drives the rear connection rod to move when working to realize the height adjustment of the automobile seat.

A vehicle seat includes a base, a cushion frame rotatably coupled to the base, a tip-up mechanism engaged to the cushion frame and the base and configured to rotate the cushion frame with respect to the base, a cushion front frame rotatably coupled to a front portion of the cushion frame, and a tilting mechanism engaged to the cushion front frame and the cushion frame and configured to rotate a rear of the cushion front frame upward and forward with respect to the cushion frame.

In a seat adjustment apparatus and system for a mobility vehicle and a method of controlling the same, a position and shape of a seat are automatically adjusted and optimized for an occupant based on the occupant's body type, whether the occupant is accompanied by a pet dog or item, whether an auxiliary device such as a wheelchair is used, and the like so that convenience for the occupant may be improved, and a position of a backrest portion and a position of a cushion portion may be adjusted, as necessary, which may minimize a useless space, and in which a state and situation of the occupant are optimized, and the position of the backrest portion and the position of the cushion portion are adjusted so that the satisfaction of the occupant in a compartment space may be ensured.

A lifting mechanism for a seat, a seat, and a vehicle. The lifting mechanism for the seat includes a fixing frame, a seat frame including a front end rotatably connected to the fixing frame; and a drive assembly installed to the fixing frame and configured to drive the seat frame to rotate around the front end.

A car seat for road cars has a seat; and an operating assembly to selectively control a height and an inclination of the seat relative to a support frame of a road car; the operating assembly having a pair of rear connecting rods coupled in a rotary manner to the seat and to the support frame, a pair of variable-length front connecting rods coupled in a rotary manner to the seat and to the support frame to selectively control the inclination of the seat relative to the support frame, and an actuator device to rotate the rear and front connecting rods and to selectively control the height of the seat relative to the support frame.

An embodiment relaxation seat for a vehicle includes a seat cushion lower frame configured to be mounted on a seat rail, a seat cushion upper frame connected to the seat cushion lower frame in a tilting-enabled manner, a seat back frame connected to the seat cushion upper frame, a locking device mounted at a predetermined position on the seat cushion upper frame, a front link hinge-connecting between the seat cushion upper frame and a front end portion of the seat cushion lower frame, a rear link hinge-connecting between the seat cushion upper frame and a rear end portion of the seat cushion lower frame, and a support bar connecting between the locking device and the front link in a manner that is movable backward and forward and configured to support the front link for rotation or fixation thereof.
