Embodiment Construction

[0034] Image 6 The motor vehicle 1 shown has an electric motor and / or an internal combustion engine (not shown) for driving the motor vehicle. The motor vehicle 1 has in the vehicle interior two front seats 2 and three rear seats 3 , which are designed as rear seats with three rear seats 3 . Seat belt retractors 4 are mounted or integrated in the C-pillar of the motor vehicle 1 on both lateral rear seats 3 . The seat belt 5 for the two side rear seats 3 can be rolled up or unwound by the seat belt retractor 4, wherein the seat belt 5 is designed as a belt with pelvis and shoulder belts (not shown) Three-point safety belt 5.

[0035] exist Figure 1 to Figure 4 A first exemplary embodiment of a seat belt retractor 4 for a rear seat 3 of a motor vehicle 1 is shown in . The belt retractor 4 includes a receiving part 6 which is designed as a roller 7 or as a coil 8 . The receiving part 6 is mounted rotatably about an axis of rotation 9 by means of bearings (not shown), so th...

Abstract

The invention relates to a seat belt rewinder for a car, especially for a rear seat of a car, which includes a seat belt retractor, a seat belt wound on the receptacle, and a device for detecting the seat belt rewinder or the deceleration of the car. A deceleration sensor and / or a first pull-out speed sensor that detects the pull-out speed of the seat belt before activating an energy absorbing device for fixing the seat belt by energy absorption and in conjunction with the deceleration sensor and / or the first pull-out speed sensor Effectively connected and thus fixing the seat belt by energy absorption when the deceleration limit value is exceeded and / or when the first pull-out speed limit value is exceeded, the seat belt rewinder includes a locking mechanism for fixing the seat belt without energy absorption and a detection seat belt A second pull-out speed sensor for the pull-out speed after the energy absorption device has been activated is operatively connected to the locking mechanism, so that when the second pull-out speed limit value is exceeded, the safety belt is fixed by the locking mechanism without energy absorption.

Description

technical field [0001] The invention relates to a safety belt retractor for automobiles, especially for the rear seats of automobiles, comprising a seat belt receptacle, a seat belt wound or capable of being wound on the receptacle, and used for detecting A deceleration sensor for the seat belt retractor or the deceleration of the vehicle and / or a first extension speed sensor for detecting the extension speed of the seat belt before activating the energy absorption device for passing through the The energy absorber secures the seat belt and is operatively connected to the deceleration sensor and / or the first pull-out speed sensor so that in an accident the deceleration limit detected by the deceleration sensor and / or the first pull-out speed sensor is exceeded At the first pull-out speed limit, the seat belt is secured by energy absorption. The invention also relates to a method for operating a seat belt retractor of a motor vehicle, in particular a seat belt retractor accord...
