Problems solved by technology

[0004] This device has the disadvantage that the roller blind material can be wound and unrolled only by using a drive motor that can keep the roller blind assembly in its stowed position against the force of the spring element
In addition, at the beginning of the unwinding operation, during unwinding of the roller shade material from the winding shaft, the spring element causes unwinding to take place at an increased speed, but in some cases this may not be suitable
In addition, roller blind devices necessitate a rod between the winding shaft and the tie rod, at least in the form of a pivot arm, which is arranged on the free end of the roller blind, which makes the roller blind assembly inflexible and therefore Not practical for use as a cargo space cover

Embodiment Construction

[0025] Like features in the figures are indicated by like reference numerals.

[0026] Figure 1 shows a perspective view of the components of a roller shade assembly for returning roller shade material (not shown in the figure) in a defined manner to a stowed position at a reduced speed at the end of a winding operation. Although not shown in the figures, the roller blind assembly can be arranged in a known manner between the covering position and the storage position by winding the roller blind material on the winding shaft 1 . The roller blind assembly forms in particular a cargo space covering device for the cargo space of a motor vehicle. However, the roller blind assembly can also be used in any other application, for example as a roller blind assembly for a vehicle or a windshield for a window.

[0027] According to an exemplary embodiment of the invention, the roller blind assembly is preferably wound by means of a spring drive (not shown), which can be arranged inside...

Abstract

The present invention relates to a roller blind system, in particular to a trunk covering device for a vehicle. The roller blind system includes a roller blind material which can be wound on a winding shaft (1) between a covering position and a stowed position. The system is provided with a buffering mechanism (2). At the end of the winding process, the buffering mechanism returns the roller blind material to the storage position in a limited deceleration manner. The buffer mechanism (2) is adapted to reduce the rotation speed of the winding shaft (1) and make the rotation of the winding shaft (1) stationary within a predetermined rotation angle of the winding shaft (1).

Description

technical field [0001] The present invention relates to a roller shade assembly, and in particular to a cargo space covering device for the cargo space of a motor vehicle, having a roller shade material that can be rolled between a covering position and a stowage position Wound on the winding shaft so that damping means are provided for allowing a defined retraction of the roller shade material into the stowed position at a reduced speed at the end of the winding operation. Background technique [0002] Such a common roller blind assembly is known, for example, from DE 10242173 A1. The roller blind assembly described therein is provided for a rear windshield of a motor vehicle and has at least one pivot arm, which serves to fix the roller blind and is hinged at one end in the region of the winding shaft. The other end of the pivoting arm is force-guided as a pivotable pivot point, after a preselected movement distance, during the transfer from the pivoting arm fixed positio...
