Abstract

A seating system for a vehicle includes a seat-back frame and a backboard attached to the seat-back frame. An attachment arrangement includes an elongated member attached to the seat-back frame and the backboard, and is configured to remain attached to the seat-back frame and the backboard by plastically deforming when the seat-back frame and the backboard are subjected to a separation force of a predetermined magnitude greater than a magnitude otherwise required to detach the elongated member from the backboard.

First claim

What is claimed is:

1. A seating system for a vehicle comprising:
a seat-back frame;
a backboard attached to the seat-back frame; and
an attachment arrangement including an elongated member fastened to the seat-back frame and fastened to the backboard with a first connection feature having a first connection strength, the elongated member being configured to plastically deform such that the elongated member remains attached to the seat-back frame and the backboard when the seat-back frame and the backboard are subjected to a separation force of a predetermined magnitude greater than the first connection strength.

2. The seating system of claim 1 , wherein the attachment arrangement further includes a plurality of fasteners separate from the elongated member, at least some of the fasteners providing a respective connection strength between the backboard and the seat-back frame that is less than the separation force of the predetermined magnitude.

3. The seating system of claim 1 , wherein the elongated member is fastened to the backboard at a first location on the elongated member and fastened to the seat-back frame at a second location on the elongated member, and wherein at least one of the seat-back frame or the backboard includes an aperture configured to cooperate with the elongated member such that at least one of the first location of the elongated member is positioned relative to a corresponding first location on the backboard or the second location of the elongated member is positioned relative to a corresponding second location on the seat-back frame.

4. The seating system of claim 1 , wherein a length of the elongated member defines a longitudinal axis, and the elongated member includes a projection extending outward at an angle from the longitudinal axis and configured to cooperate with an aperture in the seat-back frame or the backboard to dispose the elongated member at a predetermined position relative to the seat-back frame or the backboard.

5. The seating system of claim 4 , wherein a width of the elongated member defines a transverse axis, and the projection is formed along the transverse axis over less than all of the width.

6. The seating system of claim 1 , wherein the elongated member is configured to deflect when the separation force of the predetermined magnitude is at least 432 N.

7. The seating system of claim 6 , wherein the elongated member comprises a steel material having a yield strength of no more than 185 MPa.

8. A seating system for a vehicle comprising:
a seat-back frame;
a backboard attached to the seat-back frame; and
an attachment arrangement including an elongated member attached to the seat-back frame and the backboard, the elongated member being configured to remain attached to the seat-back frame and the backboard by plastically deforming when the seat-back frame and the backboard are subjected to a separation force of a predetermined magnitude greater than a magnitude otherwise required to detach the elongated member from the backboard.

9. The seating system of claim 8 , wherein the separation force of the predetermined magnitude is between 432 N and 1602 N.

10. The seating system of claim 8 , wherein at least one of the seat-back frame or the backboard includes an aperture configured to cooperate with the elongated member such that the elongated member is positioned at a desired location relative to at least one of the seat-back frame or the backboard.

11. The seating system of claim 8 , wherein the elongated member includes a projection extending outward at an angle therefrom and configured to cooperate with an aperture in the seat-back frame or the backboard to position the elongated member at a desired location relative to at least one of these frame or the backboard.

12. The seating system of claim 11 , wherein the elongated member includes two end portions and a central portion, and the projection extends from the central portion.

13. The seating system of claim 12 wherein the elongated member has a first width at the end portions and a second width at the projection that is less than the first width.

14. The seating system of claim 8 , wherein the elongated member comprises a material having a yield strength of 185 MPa or less.

15. A seating system for a vehicle comprising:
a seat-back frame;
a backboard attached to the seat-back frame; and
an attachment arrangement including an elongated member attached to the seat-back frame and the backboard and comprising a material having a yield strength of no more than 185 MPa, the elongated member being configured to remain attached to the seat-back frame and the backboard when the seat-back frame and the backboard are subject to a separation force of between 432 N and 1602 N.

16. The seating system of claim 15 , wherein the elongated member is attached to the backboard with a connection feature have a connection strength less than 432 N.

17. The seating system of claim 15 , wherein the elongated member is fastened to the backboard at a first location on the elongated member and fastened to the seat-back frame at a second location on the elongated member, and wherein at least one of the seat-back frame or the backboard includes an aperture configured to cooperate with the elongated member such that at least one of the first location of the elongated member is positioned relative to a corresponding first location on the backboard or the second location of the elongated member is positioned relative to a corresponding second location on the seat-back frame.

18. The seating system of claim 15 , wherein a length of the elongated member defines a longitudinal axis, and the elongated member includes a projection extending outward at an angle from the longitudinal axis and configured to cooperate with an aperture in the seat-back frame or the backboard to dispose the elongated member at a predetermined position relative to the seat-back frame or the backboard.

19. The seating system of claim 18 , wherein a width of the elongated member defines a transverse axis, and the projection is formed along the transverse axis over less than all of the width.

20. The seating system of claim 15 , wherein the elongated member comprises a steel material.
