Problems solved by technology

[0006] However, the problem is that the seat belt retractor, with its other components, has a relatively large construction space requirement due to its external dimensions, so that installation in a vehicle seat can be problematic
This larger belt reel is due to the correspondingly large frame of the seat belt retractor and due to at least one first and second assembly, such as the drive of the non-reversible seat belt tensioner, the reversible seat belt tensioner motors, force limiting devices, sensor devices or the like further increase towards the outside, whereby the installation space requirement increases again

Embodiment Construction

[0028] exist figure 1 with Image 6 In the figure, a seat belt retractor 40 according to a preferred embodiment of the invention can be seen, which has a seat belt 12 which can be wound on a seat belt reel 14 . The belt retractor 40 has a housing 7 comprising two spaced apart housing parts 8 and 9 and a housing intermediate part 10 arranged between the housing parts 8 and 9, for better identifiability, already in Image 6The housing intermediate piece 10 is omitted in the illustration. The housing parts 8 and 9 and the housing intermediate part 10 are configured as an elongated U-shaped profile and are arranged such that the two spaced apart housing parts 8 and 9 surround each other by less than 180° with their longitudinal axes D. degrees but greater than 90 degrees and are connected to each other through the housing intermediate piece 10 . The open sides of the housing parts 8 and 9 and of the housing middle part 10 are each covered by a cover part 13 to form a closed pr...

Abstract

The invention relates to a seat belt retractor (40). The seat belt retractor (40) has a belt spool (14), a seat belt (12) that can be wound thereon to a belt spool, and at least a first and a second assembly (1, 2), wherein the first and the second assembly (1, 2) are arranged coaxially to each other and at a first angle (A) to the rotational axis (B) of the belt spool (14) and are connected together by a flex coupling or an angular gear.

Description

technical field [0001] The invention relates to a safety belt retractor. Background technique [0002] The belt retractor has, as a basic component, a load-bearing frame and a belt reel rotatably mounted in the frame, on which the belt can be wound. In addition to supporting the belt reel, the frame is also used for fastening to the seat structure or to the vehicle structure and for this purpose is produced from a correspondingly thick steel sheet which is bent into a U-shaped frame. [0003] Vehicle seats with belt arrangements are known, for example, for use as front seats in convertible cars, wherein at least a belt retractor of the belt arrangement is fastened to the backrest of the vehicle seat. In this case, the seat belt retractors are preferably integrated into the backrests of the vehicle seats due to the lack of load-carrying B-pillars and for reasons of access to the rear seats or for reasons of remoteness from the rear vehicle structure. It must therefore also ...
