A side-impact crash structure for a vehicle seat may be positioned in the side wall of a passenger seat to reduce impact forces imparted to an occupant during a side collision. The side-impact crash structure for the vehicle seat may include energy absorbers positioned between the seating surface and the outer sidewall of the vehicle. The energy absorbers may be positioned to engage the shoulder and/or lower abdomen area of the passenger. The energy absorbers may be configured to absorb impact forces over a limited ride-down distance (the distance over which the deceleration occurs) to prevent injury to occupants.

A modular seat assembly includes a seat frame, a modular seat component for engaging the seat frame including a mounting bracket, a cable routed towards the frame and engaged with the mounting bracket, and a cable tensioning system. The cable tensioning system is configured to tighten the cable into a tensioned state and release the cable into a slacked state. In the tensioned state, the modular seat component is secured to the seat frame via engagement of the cable with the mounting bracket, and in the slacked state, the modular seat component is releasable from the cable via disengagement of the cable from the respective mounting bracket.

A vehicle seat device includes: a base member provided in a seat cushion or a seat back; a movable member rotatably connected to the base member; and stopper parts disposed to abut against each other on the base and movable members. The movable member rotates from a storage position and the rotation of the movable member is restricted at a deployment position so that a seat mode is changed. The vehicle seat device further includes an air bag interposed between the base and movable members and presses the base and movable members to rotate the movable member; and a clutch mechanism interposed between the base and movable members, allowing the rotation of the movable member in a deployment direction, and restricting the rotation of the movable member in a storage direction.

A vehicle seat includes a first heater which heats a first region, a second heater which heats a second region different from the first region, and a controller connected to the first heater and the second heater. The controller is capable of executing PWM control under which current applied to the first heater and the second heater is regulated by setting current-application timeframes within a unit time period, wherein a first current-application timeframe that is a period within the unit time period in which current is applied to the first heater and a second current-application timeframe that is a period within the unit time period in which current is applied to the second heater, as set under the PWM control, are shifted relative to each other when current is applied to the first heater and the second heater.

A vehicle seat that can suitably protect a seated occupant against an impact from a seat width direction is described, while enlargement of the seat in the seat width direction is restrained. A support member provided to the vehicle seat supports the seated occupant from a side of the seated occupant, and includes an inner plate attached to a seat width direction inner side of a side frame, an outer plate attached to a seat width direction outer side of the side frame, and a connection plate for connecting the inner plate and the outer plate on a seat front side. The outer plate is attached to the seat width direction outer side of the side frame at a position that does not overlap in the seat width direction with attachment positions of the inner plate and the side frame.

A vehicle occupant protection structure includes a seat body including a seatback configured to support a back of an occupant, and a shell section including a portion configured to face a side of the occupant whose back is supported by the seatback and the portion configured to restrict movement of the occupant in a seat width direction in a case of a vehicle collision.

In embodiments, an aircraft passenger seat assembly includes a seatback assembly including one or more lateral seatback sections. In embodiments, at least one lateral seatback section includes a base seatback panel coupled to a seatback frame, a first set of segmented seatback panels coupled to the base seatback panel, and a second set of segmented seatback panels coupled to the first set of segmented seatback panels. In embodiments, the aircraft passenger seat assembly further includes a plurality of actuatable assemblies, wherein the plurality of actuatable assemblies include a first set of actuatable assemblies configured to selectively actuate the first set of segmented seatback panels relative to the base seatback panel, and a second set of actuatable assemblies configured to selectively actuate the second set of segmented seatback panels relative to the first set of segmented seatback panels.

A conveyance seat capable of suppressing wrinkles or saggings from occurring on a surface of a seat main body is provided. A conveyance seat S includes a seat back and a movable body which is attached inside the seat back, is disposed at an outer position in relation to a center portion of the seat back, and is operated so that a side portion of the seat back protrudes toward a seated occupant side (seat front side). The movable body is disposed on a back surface of a cushion material in the side portion. An end portion (rear end portion) on the side opposite to the seated occupant side of the movable body is disposed on the seated occupant side (seat front side) in relation to a seating surface of the center portion of the seat back.

A seat belt positioning mechanism that has a vehicle seat and an elastic tensioning member. The vehicle seat has a frame structure, a cushion portion covering the frame structure and a cover material covering the cushion portion. The cushion portion defines a main seating section and an outboard side seat section extending laterally outboard from a corresponding side of the main seating section. The side seat section defines an opening extending through the cushion portion. The opening is dimensioned to receive a seat belt extending therethrough. The cover material has a cover extension extending into the opening. The elastic tensioning member has a first end fixed to the frame structure and extends under the cover extension into the opening. The elastic tensioning member is dimensioned and shaped to bias the cover extension in an outboard direction against a part of the seat belt located within the opening.

A vehicle seat includes a first heater which heats a first region, a second heater which heats a second region different from the first region, and a controller connected to the first heater and the second heater. The controller is capable of executing PWM control under which current applied to the first heater and the second heater is regulated by setting current-application timeframes within a unit time period, wherein a first current-application timeframe that is a period within the unit time period in which current is applied to the first heater and a second current-application timeframe that is a period within the unit time period in which current is applied to the second heater, as set under the PWM control, are shifted relative to each other when current is applied to the first heater and the second heater.
