An occupant protection device including: a side support section; a lumbar support section that is provided to the width direction intermediate portion of the seatback, and that has a support face displaceable between an advanced position pressing the lumbar region and a retreated position further to a seatback rear side than the advanced position; a displacement mechanism that displaces the support face of the lumbar support section between the advanced position and the retreated position; a side collision prediction section; an actuation controller that, in a case in which a vehicle side-on collision has been predicted by the side collision prediction section in a state in which the support face of the lumbar support section is not at the retreated position, controls the displacement mechanism so as to displace the support face of the lumbar support section to the retreated position.

In a vehicle seat, a gas generating device of a side airbag apparatus is attached to the inside of an outer side frame in a seat-width direction. When a seated occupant is a three-dimensional mannequin of AM50, a portion of the gas generating device overlaps a back pan of the three-dimensional mannequin as viewed in a seat front-rear direction. Here, in a plan section of a seat back in a range in which the gas generating device is positioned in a seat up-down direction, when an imaginary line overlapping a section of the back pan is moved back toward a seat rear side until the imaginary line comes into contact with a side spring portion of a seat back spring, the gas generating device is positioned rearward of a moved-back imaginary line in the seat front-rear direction and outward of the moved-back imaginary line in the seat-width direction.

A support for an armrest assembly includes a plurality of interconnected ribs. One or more of those ribs has (a) a first section, having a first proximal end and a first distal end, (b) a second end section, having a second proximal end and a second distal end, and (c) an intermediate section connecting the first distal end and the second distal end. The first end section and the second end section are offset. An armrest assembly includes a body, the support, a cushioning layer overlying the support and a cover layer overlying the cushioning layer.

Various seating arrangements for a vehicle are described. Generally, the vehicle includes an electromagnetic array featured on a floor of the vehicle. The chair includes base having a plurality of magnets featured thereon. The vehicle generates signals for the electromagnetic array to generate a wave and impart a force on the chair in a determined direction via the plurality of magnets.

The present invention discloses a retractable side protecting airbag for a child safety seat which includes a side protecting base provided on an outer side surface of the seat body. Specifically, the side protecting base is provided with the retractable side protecting airbag. The retractable side protecting airbag is correspondingly provided with an air deflating hole. The side protecting airbag is internally provided with a resetting structure. An outer end of the retractable side protecting airbag is provided with a side protecting cover. The protecting cover and the side protecting base are locked to each other and work collaboratively for folding the retractable side protecting airbag. The present invention has a reasonable structure and a long distance for crumpling, and is capable of providing buffering and effective energy absorption, thereby greatly reducing the damage to children from side crashes.

An armrest assembly includes a body outlining a crushable space. The body includes a first deformation initiating feature, a second deformation initiating feature, a deformation propagating feature and a fracture initiating feature provided at spaced locations around the crushable space. The features function to dissipate energy in the event of a side impact and therefore force or load that might be transmitted to a motor vehicle occupant as a result of a side impact.

An assembly includes a seat and an armrest moveable relative to the seat. A first arm and a second arm each include a first hinge and a second hinge. The first hinges are spaced from each other and fixed relative to the seat. The second hinges are spaced from each other and fixed relative to the armrest.

The present disclosure discloses an apparatus comprising: a backrest; a side impact protection block movably fitted to the backrest between a folding position and an unfolding position; and a self-locking structure fitted to the side impact protection block or the backrest, the self-locking structure being configured to block the side impact protection block in the unfolding position from switching to the folding position. The self-locking structure comprises a self-locking member and a self-locking reset member, the self-locking member being fitted to the backrest or the side impact protection block, the self-locking reset member being configured to apply a force to the self-locking member to drive it into an extended position that blocks the side impact protection block in the unfolding position from switching to the folding position.

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 vehicular seat includes a first conduit that guides gas from a first gas generator to a first airbag, the first conduit includes a first flexible tube portion having flexibility and disposed along a first side end inside at least one of a seat surface or a seat back, and the first flexible tube portion expands to deform the seat body when the gas supplied to the first airbag from the first gas generator passes through the first flexible tube portion.
