Abstract:
The invention relates to a roller blind system for a motor vehicle with at least one roller blind web (10) and at least one winding tube (12) for winding the roller blind web in and out, the roller blind web having at least one flexible flat guide strip (18) along each lateral edge portion, which extends in the deployment direction of the roller blind and is guided in a track (20). According to the invention the track contains a slot in which the guide strip is guided, and which has an exit gap (22) through which the roller blind web exits the guide, the guide strip being guided in such a way that its base surface (31) is essentially parallel to the adjacent portion of the roller blind web. The shape and dimensions of the exit gap and guide strip are such that the guide strip cannot come out of the track by itself. The invention also relates to a roller blind system for a motor vehicle with at least one roller blind web (10) and at least one winding tube (12) for winding the roller blind web in and out. According to the invention the roller blind web (10) is connected to the winding tube (12) by at least one constant-force spring comprising a spirally wound spring element made of a flat strip (18), the end of which is connected to the winding tube. The invention further relates to a roller blind system for a motor vehicle with at least one roller blind web (10) and at least one winding tube (12) for winding the roller blind web in and out, wherein at least one winding tube is formed by a constant-force spring which is connected to the roller blind web and comprises a spirally wound spring element made of a flat strip (18), the innermost end of which forms at least one winding for winding in the roller blind web in any of its working positions.
Abstract:
The invention relates to a vehicle roof (10) comprising at least one at least partially transparent roof part (14) that can be moved in order to at least partly open a roof opening (17), and a blind (20) which allows the movable roof part (14) to be covered from below at least in the closed position of the roof part (14). Said blind (20) is equipped with a blind web (22), an extensible hoop that is arranged at the front edge of the blind web (22), and a blind shaft (26) for winding up the blind web (22). The extensible hoop (24) is coupled to an electric driving motor via a dog so as to displace the extensible hoop along a guide. In order to make the vehicle roof more comfortable to operate, the extensible hoop (24) is removably coupled to a dog which is connected to the driving motor such that the blind (20) can be operated with the aid of the driving motor and can be displaced manually without being coupled to the driving motor.
Abstract:
The sensor has a piezoelectric crystal for converting impulse of drop through compression into an electrical signal, where amplitude of the signal is an expression of the impulses of drops and piezoelectric units made of piezoelectric crystal. A cover plate protrudes over a base plate, where a measuring surface is grounded off through a tension spring to the base plate. The measuring surface exhibits the cover plate to overlie on the piezoelectric units. An independent claim is also included for a cover plate for use in sensor.
Abstract:
The invention relates to a blind assembly comprising a blind web (11) which is provided with one respective flexible, flat guide strip (10) along both lateral edge areas. Said guide strip (10) is guided inside a guide along the direction of extension of the blind in order to stretch the blind web. The base of the guide strip (10) is guided parallel to adjacent areas of the blind web. The inventive blind assembly further comprises at least one blind coupling with which at least one of the guide strips engages in a removable, positive manner via an entraining element (12) and via which the guide strip can be extended along with the blind web.
