Problems solved by technology

Here too, the excessive construction effort caused by the external drive mechanism including the associated components has proven to be disadvantageous, which leads to expensive head restraints
It is difficult to achieve the sought-after headrest or vehicle seat with a compact structure, since additional components must also be installed on the headrest or vehicle seat

Embodiment Construction

[0047] Figure 1a The upper region of a vehicle seat 1 is shown, from which backrest 2 protrudes two retaining rods 3 for fastening a head restraint 4 according to the invention. The vehicle occupant's head 5 and cervical spine 6 can be seen in front of the head restraint 4 , the torso of which is indicated by reference numeral 7 .

[0048] exist Figure 1a Also shown are three spatial axes arranged perpendicularly to each other, wherein the spatial axis facing horizontally in the direction of travel is denoted by X, the vertical spatial axis is denoted by Z, and the spatial axis oriented transversely to the direction of travel is denoted by Y. The axes X and Z here form the median plane with respect to the vehicle occupants.

[0049] Figure 1a The situation before the accident is shown, in which the head 5 has a clear distance from the head restraint 4 . The area of ​​the head restraint 4 located behind the head 5 in the direction of travel has a central impact zone 8, the ...

Abstract

The invention relates to a headrest of a vehicle seat (1) with a deformable central support forming an impact zone (8) for the head (5) of a vehicle occupant, in the event of an accident In this case, the kinetic energy of the head (5) is introduced into the support body. On both sides of the impact zone (8), lateral support surfaces (9) are attached to the central support body, which protrude from the plane of the headrest (4) in the direction of travel (X) for lateral Support the head (5) firmly. In order to avoid or at least reduce the risk of cervical dislocation trauma, it is proposed according to the invention that the headrest ( 4 ) includes means for absorbing the energy introduced into the central support ( 8 ) and for outputting the absorbed energy in order to activate the lateral The mechanism of the support surface (9).

Description

technical field [0001] The invention relates to a head restraint for a vehicle seat, with a deformable central support forming an impact zone for the head of a vehicle occupant, in the event of an accident the head Kinetic energy is introduced into this central support body; lateral support surfaces connected to the central support body on both sides can be moved out of the plane of the headrest for lateral support of the head. Background technique [0002] A common injury in motor vehicle accidents, especially impact accidents, is cervical dislocation trauma (HWS-dislocation trauma). The reason for this is that in the event of an accident, due to the sudden acceleration of the vehicle occupant in the direction of travel, an extreme extensional movement of the head occurs, while at the same time a torsional movement and pivoting about usually several spatial axes takes place. As a result, the upper neck muscles close to the spine twist excessively, eventually causing a so-c...
