A high-strength steel sheet comprises, by weight, not less than 0.25% and not more than 0.5% of C, not less than 4% and not more than 14% of Mn, not less than 6.5% and not more than 9.5% of Cr, and not less than 0.3% and not more than 3% of Si. The high-strength steel sheet satisfies formulas 1 and 2, formula (1) being 12&#x2266;2.0Si+5.5Al+Cr+1.5Mo&#x2266;25 and formula (2) being 13&#x2266;30C+0.5Mn+0.3Cu+Ni+25N&#x2266;17, and mainly consists of austenite, and the high-strength steel sheet has yield strength of not less than 1000 MPa and total elongation of not less than 20%. In formulas 1 and 2, each element in the above formulas indicates the content, in weight %, of the element.

High-strength steel sheet and the method for production therefor

An automobile hood has a skin and a frame reinforcing it. At least part of a space defined between the skin and the frame is packed with a foamed metal which breaks down continuously upon receiving an external force. Its continuous breakdown absorbs a substantially equal amount of impact energy continuously.

Automobile hood

A seat having a seat back and a seat cushion, the seat back including a first frame and a first support member stretched within the first frame, the first support member being made of a first elastic body, the first elastic body including a first section having first tension suitable for supporting a person sitting on the seat, and second sections having second tension lower than the first tension.

Seat having seat surface portion made of surface-like elastic body

A seat having a seating face made of sheet resilient material is assembled from a seat frame comprising a substantially quadrilateral frame body, the sheet resilient material forming the seating face, a pad member forming a largely rising bank, and a skin material enclosing the pad member, wherein the sheet resilient material is stretched within a frame body of the seat frame, one end of the skin material is abutted against and fixed on the frame body of the seat frame, the pad member is assembled outside the seat frame, the skin material covers outside of the pad member from the one end which is abutted against and fixed on the frame body of the seat frame, and the other end is wound and stopped around a back of the seat frame, a bank which rises larger than the surface position of the seating face made of the sheet resilient material which is stretched within the frame of the seat frame is formed, and the bank is assembled as a strong bank with a simple structure, and the pad member prevents the seat frame from touching a sitting passenger so that the sitting passenger should not feel a sense of incongruity.

Seat having seating face made of sheet resilient material

A seat is provided which comprises a generally quadrilateral seat frame and a seat cushion formed from a resilient sheet and provided bridging between lateral sides of, and inside, the seat frame. A cushion member is provided opposite to the resilient sheet and bridging between lateral sides of, and inside, the seat frame. The cushion member is deflectable, under the weight of a sitting person, along with the resilient sheet which mainly receives the weight of the sitting person on the seat.

Seat with resilient sheet-formed seat cushion

A trim cover 5 capable of vending and deforming together with the sheet resilient material by pressure of a body of a sitting passenger is stretched within the frame of the frame body such as to face a front surface side of the sheet resilient material 2. With this structure, it is possible to suppress the air from an air conditioner in a vehicle from directly flowing from the seating face to a sitting passenger, thereby preventing the excessive effect of the air conditioner in the vehicle. Further, the design of the entire seat can be enhanced.

A shock-absorbing polyurethane foam is formed of a polyol component and a polyisocyanate component. The polyol component is a mixed polyol having an average hydroxyl number of 130-250 and composed at least of 20-70 parts by weight of a low-molecular polyol having a molecular weight of 300-500 and 80-30 parts by weight of a high-molecular polyol having a molecular weight of 1,500-8,000 per 100 parts by weight of the whole polyol component. The foam further contains 5-150 parts by weight of a plasticizer having a solidification point not higher than -20.degree. C. per 100 parts by weight of the whole polyol component. The foam can be produced by reacting the polyol component and polyisocyanate component in the presence of 5-150 parts by weight of the plasticizer per 100 parts by weight of the polyol component.
