Abstract

A device for fastening a table top to a side wall of a vehicle includes: a structure for fastening to the side wall, and a support structure of the plate. The support structure includes: at least one crosspiece extending along a transverse direction, and at least two beams each extending in a longitudinal direction substantially orthogonal to the transverse direction, with the crosspiece being connected to each of the beams. The support structure includes bending onset zones configured to deform plastically when a force greater than or equal to a predetermined threshold force is applied on the support structure along the transverse direction.

First claim

The invention claimed is:

1. A device for fastening a table top to a side wall of a vehicle, the fastening device comprising:
a structure for fastening to the side wall; and
a support structure of the table top, defining a support surface extending in a substantially horizontal plane,
the support structure comprising:
at least one crosspiece extending along a transverse direction,
at least two beams each extending between a junction end to said crosspiece and a fastening end to said fastening structure in a longitudinal direction substantially orthogonal to the transverse direction,
said crosspiece being connected to each of said two beams,

wherein each of the at least two beams has a bendable onset zone configured to deform plastically when a force greater than or equal to a predetermined threshold force is applied on said support structure along the transverse direction, so that each of said two beams pivots relative to said crosspiece about a pivot axis orthogonal to said transverse and longitudinal directions when a force greater than or equal to said predetermined threshold force is applied on said support structure along the transverse direction.

2. The fastening device according to claim 1 , wherein the bendable onset zones include two first bendable onset zones, each arranged near the junction end of a respective beam of said two beams between the respective beam and said crosspiece, and two second bendable onset zones, said first and second bendable onset zones defining a substantially rectangular profile when no force is exerted on said support structure, each second bendable onset zone being arranged on a respective beam of said two beams.

3. The fastening device according to claim 2 , wherein each beam comprises a movable portion that extends from the second bendable onset zone of said beam to the junction end of said beam, and a stationary portion that extends from the second bendable onset zone of said beam to the fastening end of said beam, said second bendable onset zone of each beam allowing pivoting of the movable portion of said beam relative to the stationary portion of said beam.

4. The fastening device according to claim 1 , wherein:
the bendable onset zones comprise two first bendable onset zones, each arranged near the junction end of a respective beam of said two beams between the respective beam and said crosspiece, and two second bendable onset zones, said first and second bendable onset zones defining a substantially rectangular profile when no force is exerted on said support structure,
the fastening structure comprises two uprights each extending from the fastening end of one of said beams, substantially orthogonally to said beam, said uprights being configured to be fastened to the side wall of the vehicle, each second bendable onset zone being arranged on a respective upright of said two uprights.

5. The fastening device according to claim 4 , wherein each upright comprises a transverse wall for fastening to the side wall of the vehicle, and a longitudinal wall extending along the longitudinal direction of the transverse wall up to the fastening end of one of said beams, and each second bendable onset zone is arranged near a connecting zone between the longitudinal wall and the transverse wall of the respective upright.

6. The fastening device according to claim 1 , wherein at least one of the bendable onset zones is formed by a thinner zone of the crosspiece and/or the beam, the thinner zone having a thickness lower than an average thickness of the crosspiece and beams or formed by a zone of the crosspiece and/or beam comprising recesses.

7. The fastening device according to claim 6 , wherein the recesses are circular.

8. The fastening device according to claim 1 , further comprising:
a side angle iron configured to be fastened to the side wall opposite one end of an edge of the table top.

9. A table for a vehicle, said table including the fastening device according to claim 8 and a table top, the table top resting on the support surface, an initial gap being present between the angle iron and the table when no force is exerted on said support structure, said gap being able to decrease substantially to zero after the plastic deformation of at least one bendable onset zone, the width of the initial gap advantageously being comprised between 10 and 20 millimeters.

10. The fastening device according to claim 1 , the device being made in a single piece.

11. The table according to claim 9 , including an element for fastening the crosspiece to the bottom surface of the table top, the fastening element being located substantially at the center of the width of the table top, the fastening element being of the bracket type.
