A structure of a cushion support member including reinforcements and a joint at which the reinforcements intersect and are joined together. The reinforcements include a first reinforcement, a second reinforcement and a third reinforcement extending respectively in a first direction, a second direction adjacent to the first direction, and a third direction adjacent to the second direction. The joint has a surface showing a first join line indicating a joined part of the first and second reinforcements and a second join line indicating a joined part of the second and third reinforcements. The first and second join lines are formed of curved lines curving from one side to the other side in a thickness direction of the cushion support member, and an end of the first join line and an end of the second join line meet at a same position on the one side.

A joined body includes: a thin plate including through holes; a first member including a proximal portion having a portion contacting the thin plate, and a protruding portion that protrudes in relation to a contact surface of the proximal portion and is inserted through the through hole; and a second member arranged oppositely to the proximal portion via the thin plate and made of a material that is same as that of the first member. The thin plate is made of a material having a specific gravity smaller than that of the material forming the first and the second members. The second member and an end portion of the protruding portion are connected to each other, by a part of the second member and a part of the end portion being melt-solidified, the end portion being at a side opposite to a side connected to the proximal portion.

An adjustable swiveling passenger seat assembly is disclosed. The adjustable swiveling passenger seat assembly includes a set of base rails coupled to a floor. The adjustable swiveling passenger seat assembly further includes a plurality of pitch clevises coupled on a top surface of each of the set of base rails. The adjustable swiveling passenger seat assembly includes a swivel outer plate aligned in parallel relative to the floor. The swivel outer plate of the adjustable swiveling passenger seat assembly further includes a plurality of slots located on corners of the swivel outer plate and a plurality of spacers disposed within the plurality of slots.

A seat back system for a vehicle includes a fixed seat support member fixed relative to the vehicle, a seat back frame pivotally mounted relative to the fixed seat support member, and a torsion spring element mounted to the seat back frame. The torsion spring element includes a first end fixed relative to the fixed seat support member and a second end fixed relative to the seat back frame.

A car seat includes an actuator capable of changing an orientation of a rest surface of a seat back laterally by turning and moving at least a side portion frame that is part of the car seat frontward and rearward, and a controller configured to exercise control over the actuator. The controller includes a run-time posture support unit configured to execute a run-time posture support control under which when a car makes a turn, the actuator is regulated to cause the rest surface of the seat back to be oriented in a direction of the turn. The run-time posture support unit is configured to regulate the actuator in accordance with a placement of the seat in the car, when the run-time posture support unit executes the run-time posture support control.
