Abstract

Protection device for a vehicle interior compartment including a flexible planar structure displaceable between rest and protective positions. On a face end region of the planar structure, a dimensionally stable guiding profile is provided, which is guided in vehicle-fixed guiding tracks. Each side of the guiding profile is associated with a coupling member in operative connection with an entrainer guided in the respective guiding track by a retaining device acting in a force-limited manner. The entrainers are shiftable in mutual synchronization within the guiding tracks by a drive system. The coupling members are in operative connection to the entrainers eccentrically offset in relation to a central longitudinal axis of the guiding profile, and the coupling members are removable from the entrainers in response to external strains of the guiding profile in directional components which are orthogonal in relation to a plane of deployment of the planar structure.

Claims

1. A protection device for a vehicle interior compartment, comprising a flexible planar structure displaceable between a rest position and a protective position, the planar structure having an end region provided with a dimensionally stable guiding profile, the guiding profile being guided in vehicle-fixed guiding tracks on opposite sides thereof, each side of the guiding profile being associated with a coupling member in operative connection with an entrainer guided in the respective guiding track by a retaining device acting in a force-limited manner, the entrainers being shiftable in mutual synchronization within the guiding tracks by a drive system, the coupling members being in operative connection with the entrainers eccentrically offset in relation to a central longitudinal axis of the guiding profile, the coupling members being removable from the entrainers in response to external strains exerted on the guiding profile with directional components orthogonal to a plane of deployment of the planar structure, each retaining device being disposed on the respective coupling member or on the respective entrainer for rotation about a rotational axis oriented in parallel to the central longitudinal axis of the guiding profile, each retaining device including at least one unilaterally clamped leaf spring.

2. The protection device according to claim 1, wherein the coupling members are fixedly disposed on the guiding profile.

3. The protection device according to claim 1, wherein each leaf spring flanks an outer contour of the respective entrainer.

4. The protection device according to claim 1, wherein each retaining device is disposed on the respective coupling member.

5. The protection device according to claim 1, wherein each entrainer comprises a pin projecting inwardly in a direction transverse to the guiding tracks.

6. The protection device according to claim 5, wherein each leaf spring defines a latching recess configured to receive the pin of the respective entrainer.

7. The protection device according to claim 6, further including a housing and a winding shaft mounted for rotation within the housing, the planar structure being fixed to the winding shaft and being windable about the winding shaft and unwindable therefrom, the end region of the planar structure being fixed to the guiding profile and being a leading end region of the planar structure with respect to a direction of movement thereof, the latching recess opening in a direction towards the winding shaft.
