Vehicle seat
First Claim
1. A vehicle seat comprising a seat part and a backrest part each of the seat part and backrest part having a primary support structure and a cushion covering the primary support structure, the primary support structure of the backrest part being connected at a lower end to a rear end of the primary support structure of the seat part, the primary support structure for the backrest part having an associated auxiliary support structure spaced from it on a side facing a seated passenger constituting a backrest frame containing a cushion spring arrangement, and at least one energy absorbing structure connecting the associated auxiliary support structure with the primary support structure for the backrest part, the energy-absorbing structure being plastically deformable by action of forces resulting from an impact to reduce the spacing between the primary support structure and the auxiliary support structure.

Abstract
In the embodiment described in the specification, a vehicle seat has a framework arrangement with both backrests and seat parts on which a cushion is mounted. The framework arrangement includes a first framework and a second framework which can be displaced relative to the first framework. To reduce the risk of injury to a vehicle seat occupant in the event of rear-impact accidents and/or accidents involving a vehicle turning over, the second framework is supported from the first framework by an energy-absorption structure.

24. A vehicle seat comprising a seat part and a backrest part, each of the seat part and backrest part having a primary support structure and a cushion covering the primary support structure, the primary support structure of the backrest part being connected at a lower end to a rear end of the primary support structure of the seat part, at least one of the primary support structures having an associated auxiliary support structure spaced from it on a side facing a seated passenger, and at least one energy absorbing structure connecting the associated auxiliary support structure with the corresponding primary support structure, the energy-absorbing structure being plastically deformable by action of forces resulting from an impact to reduce the spacing between the primary support structure and the auxiliary support structure:
-
wherein the energy-absorbing structure includes a plurality of energy-absorbing elements supporting the auxiliary support structure from the primary support structure in an energy-absorbing manner; and wherein the energy-absorbing elements have different force-travel characteristics.

25. A vehicle seat comprising a seat part and a backrest part, each of the seat part and backrest part having a primary support structure and a cushion covering the primary support structure, the primary support structure of the backrest part being connected at a lower end to a rear end of the primary support structure of the seat part, at least one of the primary support structures having an associated auxiliary support structure spaced from it on a side facing a seated passenger, and at least one energy absorbing structure connecting the associated auxiliary support structure with the corresponding primary support structure, the energy-absorbing structure being plastically deformable by action of forces resulting from an impact to reduce the spacing between the primary support structure and the auxiliary support structure:
including an adjustable head restraint mounted at an upper region of the primary support structure of the backrest part and displacing means for displacing the lower end of the head restraint in response to energy-absorbing displacement of an auxiliary support structure of the backrest part. - View Dependent Claims (26, 27)
