A head restraint system may have a head restraint retainer with a first surface adapted to support a cushioning material, and a second surface opposite the first surface. The second surface may have a selectively biased clip and at least one leg. The system may also have a panel with a clip port adapted to selectively retain the clip and at least one leg port adapted to selectively retain the at least one leg. A seat having a head restraint system and a method for connecting the components of the system are also provided.

Rigidity is improved at a part where side frame pieces overlap each other in a side frame. In a vehicle seat provided with a seat back frame, a side frame 10 of the seat back frame has a first side frame piece 20 and a second side frame piece 30 partially overlapping each other in a direction of extension of the side frame 10. The side frame 10 has an overlapping part 40 where both the first side frame piece 20 and the second side frame piece 30 overlap each other. At the overlapping part 40, the side frame pieces overlap each other in a state where a plurality of closed regions 41 and 42 closed by being surrounded by both side frame pieces are formed in a cross section of the overlapping part 40 intersecting with the direction of extension of the side frame 10.

A vehicle seat with an energy absorption structure, includes a cushion side plate and an angle adjuster lower connection plate, wherein an impact groove is provided on the angle adjuster lower connection plate, and the impact groove includes a straight groove part and a circular groove part communicating each other from top to bottom. The vehicle seat further includes an energy absorption disc including an annular part, a position part and impact fracture parts connected between the annular part and the position part. A first nut is securely coupled to the cushion side plate. A step bolt is provided including a head part, a step part and a stud which are coaxially connected in sequence. The stud bolt passes through the circular groove part, the annular part and threads to the first nut to make the step part passing through the circular groove part and press-fitting with the energy absorption disc. The vehicle seat has a simple structure, convenient installation, and can absorb energy during collision so as to reduce the head rebound speed during the vehicle collision and protect passengers, thereby improving vehicle safety level.

A configuration is adopted such that the shape of a peripheral wall portion of a shell-shaped seat back skeleton can be freely set without being restricted by the presence of brackets, the incidence of warping of the seat back skeleton when a vehicle is involved in a rear-end or head-on collision is reduced, and the seat back skeleton does not lose strength even when brackets are affixed to the seat back skeleton. A seat cushion skeleton 8 and the seat back skeleton 9 are coupled by coupling means 19a, 19b, and the seat back skeleton 9 has a main body 14 facing the back of a seated passenger, and a peripheral wall part 15 provided to the peripheral edge of the main body 14. The main body 14 and the peripheral edge part 15 are formed into an integrated shell shape using a synthetic resin. The coupling means 19a, 19b have first brackets 21a, 21b that are joined to the seat back skeleton 9, the first brackets 21a, 21b being affixed by bonding to the main body 14 of the seat back skeleton 9.

A head restraint system may have a head restraint retainer with a first surface adapted to support a cushioning material, and a second surface opposite the first surface. The second surface may have a selectively biased clip and at least one leg. The system may also have a panel with a clip port adapted to selectively retain the clip and at least one leg port adapted to selectively retain the at least one leg. A seat having a head restraint system and a method for connecting the components of the system are also provided.

A vehicle seat reclining device includes a ratchet and a guide assembled to be rotatable, a plurality of pawls that are supported by a pair of guide walls provided on the guide, mesh with the ratchet, and are arranged in the relative rotation direction and restrict relative rotation between the ratchet and the guide, and a cam that moves the pawls outward. One of the pawls is a main pawl having a rattle preventing structure. The main pawl includes a bulging portion configured to abut against the pressing portion. Each of the pawls other than the main pawl do not have a bulging portion corresponding to the bulging portion of the main pawl.

Provided is a vehicle seat frame configured so that the weight of the frame can be reduced while the strength of a portion of the frame can be ensured. A vehicle seat frame F includes a frame member molded from a high tensile strength steel plate. A metal structure of a portion of the frame member is a structure formed according to one or more conditions upon a thermal treatment performed on the frame member, and the strength of the portion is different from those of other portions of the frame member. For example, the portion of the frame member includes a high strength portion with a higher strength than those of the other portions. Moreover, the portion of the frame member includes, for example, a low strength portion with a lower strength than those of the other portions.

An aircraft seat device has a multi-part backrest frame unit comprising at least one first side frame element, at least one second side frame element, which is arranged on a side of the backrest frame unit that is opposite from the first side frame element, and at least one transverse frame element which is realized separately from the side frame elements and connects the side frame elements, wherein the transverse frame element is realized at least substantially plate-shaped.

There is provided a vehicle seat (car seat) comprising a seat cushion pad (seat body) having an air passage connected to an outlet port (114), and a blower having an inlet port (113) and configured to feed air taken in through the inlet port (113) to the air passage. The blower (100) is located on the lower side of the seat cushion pad (seat body) that is opposite to an occupant's side on which an occupant is to be seated, and the inlet port (113) is directed upward that is a direction toward the seat cushion pad (seat body).

To improve workability when attaching an airbag module disposed in a side portion of a vehicle seat from a seat back side. A vehicle seat (S) includes: a side frame (13) which constitutes a side portion of a seat back frame (10); a bracket (20) which includes an attachment portion (21) attached to a side surface of the side frame (13) on a seat inner side and a back protrusion portion (22) protruding backward from the attachment portion (21); and an airbag module (30) which includes a retainer (34) fixed to the back protrusion portion (22).
