A vehicle seat includes a seatback with a back panel having a plurality of score lines defining a deflectable upper portion of the back panel. A headrest includes a housing with front and rear covers. The rear cover includes a plurality of score lines defining a deflectable lower portion of the rear cover. A trim ring is coupled between the deflectable upper portion of the seatback and the deflectable lower portion of the rear cover by one or more reinforcement brackets in assembly. The trim ring includes a plurality of notches disposed along a perimeter portion thereof. The notches of the trim ring cooperate to define deflection points of the trim ring along the perimeter thereof. The score lines and the notches of the vehicle seat provide for a dynamic impact energy management system for the seat at a head restraint thereof.

An apparatus for making a foam material body has a mold comprising at least two mold halves fittable together to form separate first and second mold cavities; a first sprue opening into the first mold cavity, and a second sprue opening into the second mold cavity. The mold parts can be moved between an open and a closed position. Foam can be injected into the first and second mold cavities through the respective sprues. A passage, for example, connects the sprue with the mold cavity. The first mold cavity and the second mold cavity are partitioned from one another in the closed position of the mold.

An adjustable headrest for motor vehicle seat. The headrest includes a support structure fixed to a backrest and a body having a front shell and a rear shell. The front shell has a front face intended for contact with the head of a user of the seat, the front face being movable relative to the support structure along a front-rear direction denoted X, over a total travel distance. The total travel distance is formed by a first travel portion provided by a mounting enabling translational movement of the body relative to the support structure while maintaining the position of the front shell relative to the rear shell substantially constant. The total travel distance is also formed by a second travel portion provided by a mounting enabling translational movement of the front shell alone relative to the rear shell.

A headrest support having a hollow cylindrical shape and into which a headrest stay is inserted, is inserted into a bracket that has a hollow cylindrical shape and is fixed to a seat back frame. A protrusion, a tip end of which is a pivot center of the headrest support, formed such that a protrusion amount thereof increases in response to insertion of the headrest stay, is provided on an outer peripheral surface of this headrest support.

There is provided a seatback frame integrally formed by resin molding, the seatback frame including: an upper side frame section that includes a headrest retaining portion that extends along a seat width direction; a pair of side frame sections that extend along a seat up-down direction; and a reinforcing section that is formed in the upper side frame section by forming plural recessed portions, at least from the headrest retaining portion to the seat width direction end portion, wherein at least one or more of the recessed portions is open toward the seat rear side so as to provide a first wall face at the seat front side; and another one or more of the recessed portions is open toward the seat front side so as to provide a second wall face at the seat rear side.

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 headrest structure for a passenger seat, a headrest cushion and passenger seat. The headrest structure comprises an adjustable headrest frame for connection to a passenger seat; and a headrest cushion mounted to the adjustable headrest frame such that the headrest cushion is moveable relative to a seat back of the passenger seat by way of the adjustable headrest frame; wherein the headrest cushion comprises a support surface facing away from the headrest frame, the support surface comprising a concave upper part and a convex bottom part relative to the passenger seat.

The present invention relates to a method for producing a viscoelastic polyurethane soft foam. The invention further relates to a viscoelastic polyurethane soft block foam or viscoelastic polyurethane soft molded foam having particularly high tensile strengths, which are produced by the method according to the invention, and to the use of said foams. The present invention further relates to polyol compositions which are suitable for the production of viscoelastic polyurethane foams.

A vehicle includes a vehicle seating assembly defining a first occupant space. The assembly includes a seat bottom and a seat back operably coupled to the seat bottom. The seat back includes a head rest area and a back panel. A display is positioned on a rear of the seat back. A first camera is positioned within the display and configured to transmit a first video signal. A human machine interface includes a screen configured to display the first video signal from the first camera.

The purpose of the present invention is to improve the ride quality of an automobile or other vehicle at low cost. A vehicle seat is provided with a seat cushion for supporting the buttocks of a rider and a seat back for supporting the back of the rider. At a substantially central position in the width direction of the seat back in a location where the back of the rider is to be supported, a recessed part or an opening extending in the vertical direction is formed.
