A support portion for a seat assembly includes, in some configurations, a first main portion and a second main portion disposed such that a gap is provided between the first main portion and the second main portion. In some configurations, the support portion includes a plurality of first extensions projecting from the first main portion away from the gap; the support portion includes a plurality of second extensions projecting from the second main portion away from the gap; the first main portion and the second main portion are configured to extend along opposite sides of a spine of a user such that the gap is aligned with said spine; and/or the plurality of first extensions and the plurality of second extensions are configured for connection with a seatback frame.

A method for actively adjusting an adjustable component in a vehicle seat includes the steps of: (1) providing a seat assembly having a seat portion with first and second side bolsters disposed on opposite sides of the seat portion, first and second adjustable components and first and second sensors disposed in the first and second side bolsters, and a controller operably coupled to both the first and second adjustable components and the first and second sensors; (2) detecting a pressure value using one of the first and second sensors; (3) determining if the pressure value exceeds a threshold value; and moving an articulating support plate of the adjustable component associated with the sensor detecting the pressure value towards an extended position from a retracted position to a degree commensurate with pressure value detected.

A method for adjusting an adjustable component in a seat assembly includes the steps of: (1) providing a seat assembly having an adjustable support plate and a sensor; (2) supporting a seat occupant on the seat assembly; (3) moving the support plate into contact with the seat occupant; (4) sensing a pressure value applied to the support plate using the sensor as the support plate contacts the seat occupant; and (5) retaining the support plate in a deployed position. The movement of the support plate is configured to cease when the pressure value is initially detected or when the pressure value exceeds a predetermined threshold.

A vehicle seat including a panel and an actuating mechanism. The panel includes an elastomeric material. The actuating mechanism is connected to the panel. The actuating mechanism is configured to alter a contour of a seating surface of the panel.

A vehicle seat includes a side frame, a cushion panel, and an insertion member. One of the side frame and the cushion panel is provided with an elastically deformed portion including an outer circumferential surface and an inner circumferential surface, the outer circumferential surface being configured to be expanded outward by insertion of the insertion member on the inner side of the inner circumferential surface. The other of the side frame and the cushion panel is provided with a recess forming portion facing the outer circumferential surface of the elastically deformed portion, the recess forming portion having an inner surface configured to be brought into pressure contact with the outer circumferential surface expanded by insertion of the insertion member.

A seat assembly for an emergency vehicle can include an adjustable base seat and backrest, a tank support assembly configured to selectively secure tanks of different sizes, and a tank clamp assembly configured to selectively secure tanks having bottom tank ends of different configurations. Slidably adjusting the base seat can cause adjustment of a recline angle of the backrest. One or more pads on the seat can be removable. The tank support assembly can include first and second tank securements and a locking member configured to rotate to selectively dispose the first or second tank securement to secure a tank. The tank clamp assembly can include a fixed foot clamp, a movable foot clamp, and an adjustment device configured to slide the movable foot clamp to selectively clamp the bottom tank ends of different sizes between the movable foot clamp and the fixed foot clamp.

A vehicle seat having at least one side bolster mounted to the vehicle door such that when the door is open the adjoining bolster moves away from the side of the seat to provide an easier path for ingress and egress from the seat.

A seat air conditioner includes a ventilation passage member disposed on a surface of a seat cushion and configured to form an air flow passage through which an air flows in a predetermined direction along the surface. The ventilation passage member includes a first ventilation port and a second ventilation port through which an inside of the air flow passage communicates with outside of the air flow passage. The ventilation passage member is provided to close communication between the inside and outside of the air flow passage, over an entire region of the ventilation passage member between the first ventilation port and the second ventilation port in the predetermined direction.

A vehicle seat that includes: a cushion frame rear portion that is rotatable around a rear portion shaft, whose axial direction is a seat transverse direction, with respect to a vehicle body floor portion; a cushion frame front portion that is connected to the cushion frame rear portion so as to be rotatable around a center fold shaft whose axial direction is the seat transverse direction and that is positioned further toward a seat front side than the rear portion shaft; a seatback frame that stands erect from a rear end side of the cushion frame rear portion; and a driving mechanism that moves the cushion frame front portion and the cushion frame rear portion relatively in a seat vertical direction between a non-reclining state and a reclining state, in which the cushion frame rear portion tilts downward and rearward with respect to the cushion frame front portion.

There is disclosed a vehicular seat element comprising a first major surface, a second major surface and a foam core element disposed therebetween. The first major surface is configured to be in contact with an occupant of the vehicle and the second major surface is configured to be in contact with a support surface of the vehicle. The first major surface comprises a rate sensitive foam element secured with respect to the foam core element. The foam core element and the rate sensitive foam element are different from one another.
