A seat back frame includes an upper frame having a first through-hole, a bracket having a second through-hole, and a holder including a first locking portion and a second locking portion. The upper frame includes a first inner edge portion, and the first inner edge portion inwardly defines an opening of the first through-hole located opposite to the bracket. The bracket includes a second inner edge portion, and the second inner edge portion inwardly defines an opening of the second through-hole located opposite to the upper frame. The first locking portion is locked to the first inner edge portion and the second locking portion is locked to the second inner edge portion to allow the first locking portion and the second locking portion to retain the upper frame and the bracket therebetween in the up-down direction.

There is provided a vehicle seat including: a seatback frame of a seatback that supports a back area of a vehicle occupant, the seatback frame including: a left and right pair of side frame portions spaced apart in a seat width direction; and an upper frame portion that joins between end portions, at a seat upper side, of the left and right pair of side frame portions in the seat width direction, a headrest that supports a head area of the vehicle occupant being supported at the upper frame portion; and a plastic deformation portion provided at the upper frame portion, the plastic deformation portion being plastically deformed and moving at least a portion of the upper frame portion toward a seat rear side together with the headrest, when a load toward the seat rear side that exceeds a predetermined value is applied to the plastic deformation portion.

A headrest device includes: a front-rear movement mechanism that moves a moving member in a seat front-rear direction with respect to a base member supported at an upper end portion of a seatback; a head support section that is coupled to the moving member so as to be capable of rotating about an axis running in a seat left-right direction, and that includes a front face configuring a support face to support a head of a seated occupant; and an angle changing mechanism that includes a link member spanning between the head support section and the base member, the link member being rotated with respect to the base member about an axis running in the seat left-right direction by the movement of the moving member so as to rotate the head support section with respect to the moving member about an axis running in the seat left-right direction.

A headrest device includes a support frame, a pillow plate, a first driving member and a first transmission member. The first transmission member includes a first transmission rod, two first connecting plates, and two elastic members. Each end of the first transmission rod is respectively provided with a first extending plate pivotally connected to the support frame with a first pivot. Each of the two first connecting plates is pivotally connected to the first extending plate with a second pivot. The headrest device has a first rotating process when there is no obstruction in its path, in which the first transmission member rotates about the first pivot relative to the support frame to tilt the pillow plate, and a second rotating process when there is an obstruction, in which the pillow plate and the two first connecting plate rotate about a second pivot relative to the first extending plate.

A vehicle control system includes a driving controller that switches between autonomous driving an manual driving of a vehicle, a seat whose form is changed between a form during autonomous driving and a form during manual driving that are different from each other, and a seat controller that controls motion of the seat when a form of the seat is changed. If the seat is in a form during autonomous driving, the driving controller does not switch autonomous driving to manual driving when controlling the vehicle.

A headrest system and a method of providing the same is disclosed. The headrest system comprises a head support unit adaptable onto a vehicle seat, a fabric member configured to envelope at least a portion of the head support unit, and a plurality of anchor members configured to retain the fabric member in a substantially staple-free fashion. The head support unit includes a pillow portion defining a head supporting surface. The fabric member includes a central portion configured to cover the head supporting surface, and a fringe portion integrally connected around the central portion. The anchor members are arranged at locations opposite to the head supporting surface, and are configured to engage selective parts of the fringe portion, so as to as to stretch the central portion substantially conformally over the head support surface of the pillow portion and substantially retain the fabric member on the head support unit.

Arrangements for safety and comfort in vehicles.

A vehicle seat for supporting an occupant in the seated position in a vehicle may include a seat module including a base and a backrest projecting upwardly from the base. The vehicle seat further includes a headrest coupled to the backrest. There may be relative movement between the headrest and backrest.

An adjustment device for a headrest includes: a frame, a tilt adjustment device serving to adjust the headrest inclination and including at least one support element for securing the headrest. The tilt adjustment device includes: a height adjustment device including at least one tube, wherein the support element is swivelable about a swivel axis at an end portion of the tube, with the tube slidably guided in the frame, enabling the headrest to be height-adjustable relative the frame, and at least one drive means connected to the height adjustment device and operatively connected to the tube for displacing same. A rod is guided inside the tube and coupled at one of its ends with the support element, a displacement of the rod relative to the tube causing the support element to swivel about the swivel axis, thereby effecting an adjustment of the inclination of the headrest.
