Abstract
A roller blind for a side window of a motor vehicle. The roller blind has a winding shaft, which is coupled via an articulated or flexible coupling mechanism to a spring drive situated outside the winding shaft. The winding shaft and the spring drive are accommodated inside a vertical window frame segment of a motor vehicle's window. The articulated or flexible coupling between the winding shaft and the spring drive makes it possible to approximate a curved path by means of two normally straight elements of the blind. Furthermore, a very flat characteristic tension curve can be achieved for the spring drive, even when the winding shaft is very short.
Claims28
A motor vehicle comprising:
- a side window surrounded by a window frame (3), said window frame (3) having a top edge (7) and a side edge (6) which together border an inner corner (8) of the side window;
- a winding shaft (25) arranged adjacent said window frame side edge (6) with one end adjacent said top edge (7);
- a blind sheet having at one edge secured to said winding shaft (25);
- a spring drive including a helical spring (39) for tensioning the winding shaft (25) in the direction of winding up of the blind sheet (21) onto the winding shaft (25),
- said helical spring (39) being arranged entirely outside the winding shaft (25) in outwardly extending relation to an end of the winding shaft (25);
- said helical spring (39) having a fixed end (41) and a take-off end (42) adjacent to the winding shaft (25);
- said helical spring (39) having an axis that forms an angle other than 180° with the axis of said winding shaft;
- and
- a coupling mechanism (27) connecting the take-off end (42) to the winding shaft (25) for enabling the helical spring (39) to drive the winding shaft while selectively mounted with their axes at an angle other than 180° to each other.
A side window roller blind for use in a motor vehicle having a side window surrounded by a window frame (3) having a top edge (7) and a side edge (6) which form an inner corner (8), comprising
- a winding shaft (25) for mounting adjacent a window frame side edge (6) with an end adjacent said top edge (7);
- a blind sheet having at one edge secured to said winding shaft (25);
- a spring drive including a helical spring (39) for tensioning the winding shaft (25) in the direction of winding up of the blind sheet (21) onto the winding shaft (25),
- said helical spring (39) being arranged entirely outside the winding shaft (25) in outwardly extending relation to an end of the winding shaft (25);
- said helical spring (39) being a fixed end (41) at one end and having a take-off end (42) at an opposite end adjacent to the winding shaft (25);
- said helical spring (39) having an axis that forms an angle other than 180° with the axis of said winding shaft;
- and
- a coupling mechanism (27) connecting the take-off end (42) to the winding shaft (25) for enabling the helical spring (39) to drive the winding shaft from a location axially outside the winding shaft while selectively mounted with their axes at an angle other than 180° to each other.
