Abstract: A rotating car seat mechanism includes a seat base, a sliding plate, a rotating plate, a guiding socket plate, an axle defining an axis of rotation and a cylindrical pivot rod. The sliding plate is placed inside a car, allowing an upper end of the cylindrical pivot rod to be positioned at the exit of the guiding socket, further enabling the rotation out of the car door and sliding the cylindrical pivot rod into the guiding socket. Due to the path defined by the guiding socket customizing the movement of the cylindrical pivot rod, the rotating plate not only rotates on the axle, but also drives the axle forward. After applying a suitable degree of motion, the rotating plate exceeds out of a narrow space of the car, whereas an opposite amount of motion enables the rotating plate to return to the original point.

Abstract: A vehicle seat 1 includes a seat unit, a lift-up unit and a long-sliding unit. The lift-up unit moves the seat unit between an interior and an exterior of a vehicle via a door opening portion that corresponds to a passenger seat position. The long-sliding unit moves the seat unit between a driver's seat position and the fellow passenger seat position. The lift-up unit moves the seat unit downward when the seat unit is positioned at the driver's seat position, so that the seat unit is located at a suitable position for driving.

Abstract: A braking mechanism to control rotational movement of a seat is disclosed. The braking mechanism may comprise a circular member (e.g., a disc or ring) that is coupled to a base assembly and a caliper, coupled to a seat assembly, to engage the circular member. In a biased position, a braking element of the caliper applies a braking force to the circular member. A user can reduce the braking force by increasing the tension on a cable coupled to the caliper. Once the braking force is sufficiently reduced, the user may rotate the seat until the desired rotational orientation is attained. Upon release of the cable, the braking mechanism re-engages to prevent further rotational movement.

Abstract: The chair frame of a swivel rocker is slidably mounted via a pair of sleeves on the arms of a pair of flexures mounted on the base of the rocker to allow the chair frame to be moved into different positions on the flexures. Bolts are used to secure the sleeves in place on the flexures. Movement of the sleeves along the flexures changes the position at which the weight of an occupant is transferred to the flexures and thereby changes the bending moments imposed on the flexures.
