Abstract

A safety seat built into a land, air or sea vehicle is provided. A structure is fixed to the vehicle and comprises vertically disposed side components that are anchored at seat-width intervals. A safety belt member is secured to the structure and has two shoulder belts and two lap belts that are joined at a fastener. A seat belt extends transversely between the side components and upwardly there along and in an upper region of the back area of the safety seat is connected to each side component. The two shoulder belts cross one another between the side components as they extend from a connection in the vicinity of a respective side component to the other side component and then to the fastener. Back belts are provided as support belts and extend from the seat belt, parallel to the side components, upwardly to the shoulder belts, where they are connected.

Claims

1. A safety seat built into a land, air or sea vehicle, said safety seat having a seating area and a back area and comprising:

a structure that is fixed to a vehicle and comprises vertically disposed side components anchored at seat-width intervals; and

a safety belt member that is secured to said structure and has two shoulder belts and two lap belts, wherein said shoulder belts and said lap belts are joined at a fastener, wherein said safety belt member, as a seat component, has a seat belt that extends transversely between said side components and upwardly along said side components and in an upper region of said back area of said safety seat is connected to each of said side components, wherein said two shoulder belts cross one another between said side components as said two shoulder belts extend from a connection in the vicinity of a respective one of said side components, to the other side component, and then to said fastener, and wherein back belts are provided as support belts and extend from said seat belt, parallel to said side components, upwardly to said shoulder belts, where said back belts are connected.

2. A safety seat according to claim 1, wherein said two shoulder belts have an inserted force limiter.

3. A safety seat according to claim 1, wherein said lap belts transition into said back belts.

4. A safety seat according to claim 1, wherein said lap belts, on opposite sides of said seating area of said safety seat, are anchored to said side components.

5. A safety seat according to claim 1, wherein sliding elements are moveably disposed on said side components, and wherein said safety belt member is attached to said sliding elements.

6. A safety seat according to claim 5, wherein said sliding elements are provided with a force limiting device.

7. A safety seat according to claim 5, wherein those of said sliding elements disposed on the same side component are interconnected by means of a spacer.

8. A safety seat according to claim 7, wherein said spacer is provided with a force limiting device.

9. A safety seat according to claim 5, wherein respective upper and lower ones of said sliding elements on opposite side components are interconnected via respective cross-bars.

10. A safety seat according to claim 9, wherein said safety belt member is attached to said cross-bars.

11. A safety seat according to claim 9, wherein said side components and said cross-bars are tubular rods.

12. A safety seat according to claim 1, wherein a textile webbing, for additional support, is connected to said safety belt member in said back area and/or in said seating area.

13. A safety seat according to claim 1, wherein respective textile webbing is provided for lateral support between said back belt of said safety belt member and segments of said seat belt that rise diagonally to a shoulder region.

14. A safety seat according to claim 5, wherein a seat platform is provided that is connected to respective lower ones of said sliding elements that are disposed on said side components.
