Problems solved by technology

[0006] However, the chairs known in the prior art have the disadvantage that for the different functions (such as seating function, holding function, anchoring of the cushion, inherent stability, etc.) special structural parts are assembled respectively or are specially designed for this purpose. Arranged devices such as seat frames, frame elements, hinge mechanisms, connecting elements for seat cushions, foam cushions, etc.
Since each such functional part also has its own weight, the seat is still relatively heavy

Embodiment Construction

[0026] exist figure 1 An exemplary embodiment of a seat 1 for a vehicle and of a lightweight construction seat 1 is shown in . The seat shown represents a rear seat for a motor vehicle, which comprises a support part 2 , wherein the support part 2 is made of a dimensionally stable material. In the sense of the invention, a dimensionally stable material is a foam which is not compressible like soft foam, but bears the weight of the seat user without significant deformation thereof. The dimensionally stable material used here consists entirely of an expanded polypropylene particle foam (EPP). Furthermore, it can be seen that the support part 2 essentially forms the entire lightweight seat 1 (except for the two upholstery layers 8 ).

[0027] The support part 2 has two seat shells 3 for each seat user. The seat shell 3 can be subdivided substantially into three seat shell sections 5 a , 6 . In the installed state (not shown), a gasket layer 8 is applied to the housing section...

Abstract

The invention relates to a lightweight seat (1) for vehicles, in particular for rear seats of motor vehicles, consisting of a carrier part (2), wherein the carrier part (2) is produced from a dimensionally stable material and integrally comprises at least one seat shell (3) for a seat user.

Description

technical field [0001] The invention relates to a lightweight seat for a vehicle according to the features of claim 1 . In particular, the invention relates to a rear seat for a motor vehicle having a dimensionally stable, preferably one-piece seat part with a soft foam upholstery. Background technique [0002] Vehicle seats - like other components and fittings in a vehicle - are increasingly required to reduce weight while achieving both functionality and comfort. An exemplary vehicle seat is known from the patent application DE 19845730 A1. The upholstery part of such a seat is formed as a backrest with a sandwich structure consisting of molded foam parts, a soft upholstery and a light metal profiled shell between them. On the rear side, the foam molding is covered by the rear wall element. Such upholstery components are basically suitable for reducing the weight of the vehicle compared to seats with a conventional steel construction. However, the chosen construction i...
