Abstract

The invention involves a supporting device for head support (10). The supporting device includes supporting tubes (11). It can be fixed on the support of the head.Area (12A, 12B), to use the supporting device (10) support in the supporting device equipped with a transport tool seat, among which at least one sleeve (15) is set in the supporting tube (11) to enhance the supporting support from the support support.Pipe (11) at least one area (25).According to the present invention, the outer surface (16) of the sleeve (15) in part of the first surrounding area (16) is in the inner surface (17) of the supporting tube (17) on the inner surface (17) in contact with the support of the supporting tubeThe surface (16) has the backbone (23), and the protruding (22) of the protruding of the inner surface (17) extends into the backburned part (23).

Description

technical field [0001] The invention relates to a support device for a head rest. Background technique [0002] To reduce weight, the support rods are manufactured as tubes. The tube is produced, for example, from a steel strip in that the steel strip is rolled into a tube and the connected end regions of the steel sheet are welded together by longitudinal seams. The weld seam is processed externally so that it does not protrude beyond the surface of the pipe. [0003] It is known from the prior art that the support tube can be reinforced with reinforcement tubes at points where the support tube is weakened, for example due to detent notches, or at points of special loads. The reinforcing tube is formed, for example, only in the region of the support tube. Such a support device is known, for example, from EP 2 281 644 B1. [0004] In the interior of the support tube, reworking of the weld seam is only possible with great effort, so the protrusion of the weld seam is usua...
