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.

The invention discloses a seat pan (20), being formed from a first thermoplastic composite material into a one-piece pan, the seat pan (20) having a weight loading portion (201), wherein at least one slot (2010) is provided in the area of the weight loading portion (201) of the seat pan (20), and covering strips (2012) are formed by overmolding on the side edges of straps (2011) separated by the slot (2010) and extending along at least a portion of the circumference of the slot (2010) so as to reinforce the straps (2011), the covering strips (2012) being made of a second thermoplastic composite material. Furthermore, the invention discloses a seat (1) comprising the above seat pan (20).

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 seat for an off-road racing vehicle including a single piece molded shell having a seat back with a head rest, side panels and a seat bottom with a thigh support, where the shell is covered by an upholstery. The seat also includes a seat cushion positioned on the seat bottom and having two foam layers, namely, a top thin foam layer and a bottom thick energy absorbing foam layer that are secured together, where the combination of the layers is capable of absorbing high energy Z-direction forces. In one non-limiting embodiment, the top layer is a methylenediphenyl isocyanate (MDI) polyurethane foam and is 12 mm thick, and the bottom layer is an open-cell energy absorbing urethane foam and is 38 mm thick.

The present invention provides a seat frame inflator including a seat frame housing portion formed of a seat frame having a hollow structure and forming an outer shell of a pressurized gas chamber, and a partition member disposed on a hollow side of the seat frame and configured to isolate the pressurized gas chamber and a gas chamber outer region from each other. The partition member is provided with a communication hole, and a closing member configured to close the communication hole. The seat frame inflator includes an opening member disposed on the hollow side of the seat frame, and configured to open the pressurized gas chamber, and a gas discharge port formed in the seat frame to face the gas chamber outer region and configured to discharge, from the gas chamber outer region to the outside, the pressurized gas flowing from the pressurized gas chamber.
