A vehicle seat including: a seat back including a top plate main part configured to support a body of a seated person from the rear side and a top plate side part configured to protrude more forward than the top plate main part to support the body of the seated person from the lateral side; a side adjuster configured to move the top plate side part between a protruding position in which the top plate side part protrudes more forward than the top plate main part and a retracted position in which the top plate side part is retracted from the protruding position; and a controller configured to, in a case where a side collision of a vehicle is detected, drive and control the side adjuster so that the top plate side part is in the protruding position.

A vehicular seat capable of housing a seat back and a seat cushion connected to the seat back in a housing floor provided in a position lower than a vehicle body floor is described. The vehicular seat includes a support base connected to the vehicle body floor and to a lower end side of the seat back, a support leg having an upper end side mounted to the seat cushion and a lower end side connectable to the support base, and a leg holding member mounted to the support base and that detachably holds the lower end side of the support leg. The seat back is connected to the support base via right and left connecting brackets disposed on sides of the seat back and having first end sides mounted to corresponding lower end sides of the seat back and second end sides pivotally connected to the support base.

A safety system for a vehicle seat in a commercial vehicle operating a vehicle seat motion actuation when the commercial vehicle is colliding with an obstacle, comprising: —at least one actuator unit that comprises at least one seat actuator to move the vehicle seat from a driving position to a safety position—at least one control unit connected to said actuator unit to control the at least one seat actuator—at least one proximity sensor connected to said control unit and configured to detect an obstacle before the commercial vehicle collides it characterized in that the control unit is provided with a calculator device retrieving specific data (Dw, Dw′, Ds, Do) to determine the requested seat's motion speed profile and the requested seat's motion triggering moment to control, upon receiving an imminent and unavoidable collision alert signal from the proximity sensor, the at least one seat actuator to move the vehicle seat to the safety position.

An active head restraint for a seating assembly of a motor vehicle comprises a structural support for a seatback of the seating assembly, a movable head restraint pad having a stowed position and a deployed position, and a linkage deployment mechanism. The linkage deployment mechanism comprises an upper and lower bar pivotally attached at a forward end to a rear surface of the movable head restraint pad and pivotally attached at a rearward end to an outer tube fixed to an upper portion of the structural support. An inner tube reciprocates within the outer tube. A trigger mechanism is operatively connected with a lower end of the inner tube and urges the inner linkage and an actuating link to a raised deployed position in response to a rear impact event. The actuating link applies an upward force to the lower bar to deploy the movable head restraint pad.

A seat-back adjustment system for a seat for a vehicle may include a frame member configured for attachment to a support structure of the vehicle, and a rack arrangement movably attached to the frame member. The rack arrangement may include an adjustment rack and a locking rack. A driving arrangement may include at least one gear intermeshing with the adjustment rack and operable to move the rack arrangement relative to the frame member, and a locking arrangement may include at least one locking element operable to engage the locking rack when the vehicle experiences at least a predetermined negative acceleration.

A vehicle seat including a controller configured to, in a case where an excessive external load in a front and rear direction, by which a first back frame part is configured to be pressed and bent toward a second back frame part, is applied to the first back frame part, adjust an inclination angle of each back frame part by driving and controlling a reclining adjuster so that the first back frame part can be pressed against the second back frame part by being bent due to the excessive external load, the first back frame part being one of a front back frame part and a rear back frame part of a seat back, and the second back frame part being another of the front back frame part and the rear back frame part.

A headrest which supports a head portion of a passenger in a vehicle rear collision is attached to an upper portion of a frame of a seatback. A blower to perform ventilation for a passenger's back is arranged at the upper portion of the frame at a position below the headrest. The blower is held at the frame via attaching members, for example. When receiving a large rearward-load from the passenger in the vehicle rear collision, the blower moves rearward relatively to the frame and the headrest according to a rearward move (a rearward swing around an upper frame, particularly) of the attaching member and the like.

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 safety system for a vehicle seat in a commercial vehicle operating a vehicle seat motion actuation when the commercial vehicle is colliding with an obstacle, comprising: at least one actuator unit that comprises at least one seat actuator to move the vehicle seat from a driving position to a safety position at least one control unit connected to said actuator unit to control the at least one N seat actuator at least one proximity sensor connected to said control unit and configured to detect an obstacle before the commercial vehicle collides it characterized in that the control unit is provided with a calculator device retrieving specific data (Dw, Dw′, Ds, Do) to determine the requested seats motion speed profile and the requested seats motion triggering moment to control, upon receiving an imminent and unavoidable collision alert signal from the proximity sensor, the at least one seat actuator to move the vehicle seat to the safety position.

The invention relates to a safety system for a vehicle seat in a commercial vehicle operating a vehicle seat motion actuation when the commercial vehicle is about to collide with an obstacle, comprising: —at least one actuator unit that comprises at least one seat actuator to move the vehicle seat from a driving position to a safety position—at least one control unit connected to said actuator unit to control the at least one seat actuator—at least one proximity sensor connected to said control unit and configured to detect an obstacle before the commercial vehicle collides it wherein the control unit, upon receiving an imminent and unavoidable collision alert signal from the proximity sensor, controls the at least one seat actuator to move the vehicle seat to the safety position
