Abstract

Protective device with a flexible sheet-like structure movable between a compactly stored position and at least one two-dimensionally extended functional position and which is provided, on an end region thereof with a dimensionally stable extension profile which, at opposite ends, has retaining profile sections mounted so as to be displaceable telescopically to a limited extent in the extension profile and acted upon outwardly in the longitudinal direction of the extension profile by a spring arrangement. Each retaining profile section is assigned a second spring arrangement which acts on the retaining profile section in the opposite direction to the first spring arrangement. The retaining profile section, in an unloaded non-operational position, is held on the extension profile in a central position, from which the retaining profile section can be shifted inward or outward in opposite longitudinal directions relative to the extension profile.

First claim

The invention claimed is:

1. A protective device for a compartment section of a motor vehicle, with a flexible sheet-like structure movable between a compactly stored position and at least one at least partially extended functional position, the sheet-like structure being provided, on an end region thereof towards a front in an extension direction, with a substantially rigid extension profile, the extension profile having retaining profile sections at respective opposite ends thereof that are mounted so as to be displaceable telescopically to a limited extent in the extension profile and that are each acted upon outwardly in a longitudinal direction of the extension profile by a first spring arrangement, and a second spring arrangement acts on each retaining profile section inwardly in an opposite direction to the first spring arrangement, each retaining profile section, in an unloaded non-operational position, being held on the extension profile in a central position, and each retaining profile section being shiftable inward or outward in opposite longitudinal directions relative to the extension profile.

2. The protective device as claimed in claim 1 , wherein the first and second spring arrangements, are designed with spring forces of identical magnitude.

3. The protective device as claimed in claim 1 , wherein the protective device further includes a stop ring mounted on each retaining profile section in an axially fixed manner relative thereto and centrally between the corresponding first and second spring arrangements, the first and second spring arrangements being disposed to selectively bear on the stop ring.

4. The protective device as claimed in claim 3 , wherein the first and second spring arrangements are designed as helical springs having respective end regions directed toward the stop ring of the respective retaining profile section, each end region including a support ring, the support rings flanking opposite axial sides of a stop web arranged axially rigidly on the extension profile, the support rings being disposed to selectively bear axially on the stop web.

5. The protective device as claimed in claim 4 , wherein an inner contour of the stop web of the extension profile is arranged at a radial distance from an outer radial contour of the stop ring movable with the retaining profile section to allow the stop ring to move axially past the stop web.

6. The protective device as claimed in claim 1 , wherein the retaining profile sections are operatively connected axially to the extension profile by energy-absorbing deformation elements.
