Abstract

The invention relates to a module cover (40) for an airbag (10) and/or an airbag module for being arranged beneath a vehicle roof (56), especially in the area of an upper windscreen rim, wherein the module cover (40) comprises a module cover panel (41) having a rear side (42) pointing to the vehicle roof (56) during use and a front side (43) pointing away from the vehicle roof (56) during use. In accordance with the invention, the module cover panel (41) comprises an elongate clearance portion (44) preferably formed over the entire width (B) of the module cover panel (41) in the form of an elongate indentation (49) configured in the front side (43) of the module cover panel (41).

3. The module cover (40) according to claim 1, wherein the wall thickness (d) of the module cover panel (41) in the clearance portion (44) is configured to be continuous in a longitudinal section.

4. The module cover (40) according claim 1, wherein the elongate indentation (45) has a curved shape.

5. The module cover (40) according to claim 1, wherein the shape of the elongate clearance portion (44), and the shape of the elongate indentation (45), are configured corresponding to the vehicle interior.

6. The module cover (40) according to claim 1, wherein the elongate indentation (45) is arranged in parallel to a fastening edge (47) of the module cover panel (41) and/or to a free end (48) of the module cover panel (41), wherein the free end (48) of the module cover panel (41) is formed to be opposed to the fastening edge (47).

7. The module cover (40) according to claim 6, wherein the fastening edge (47) of the module cover panel (41) is an edge bent and/or curved from the front side (43) which during use points to the direction of the vehicle roof (56).

8. The module cover (40) according to claim 7, wherein a depth (d) of the elongate indentation (45) is ¼

to ¾

of the height (H) of the fastening edge (47).

9. The module cover (40) according to claim 6, wherein a longitudinal extension (I) of the clearance portion (44) is ¼

to ⅓

of a length (L) of the module cover panel (41) from the fastening edge (47) to the free end (48).

10. The module cover (40) according to claim 6, wherein the free end (48) of the module cover panel (41) includes a beading (61) and/or is outwardly bent at least in a semicircular shape.

11. The module cover (40) according to claim 1, further comprising laterally formed clamping and/or latching portions (51).

12. An arrangement of a module cover (40) according to claim 1, between a vehicle roof (56) and a vehicle roof lining (58), wherein a sun visor (60) having at least one fixing means is arranged on the vehicle roof lining (58) so that the at least one fixing means is arranged in an area of the elongate clearance portion (44) and/or an axis of movement (A) of the sun visor (60) extends within the elongate clearance portion (44).

13. An airbag module for being arranged beneath a vehicle roof (56) in an area of an upper windscreen rim, comprising a module cover (40) according to claim 1.

14. A vehicle safety system comprising a module cover (40) and/or comprising an airbag module according to claim 13.

15. The vehicle safety system according to claim 14, wherein the module cover (40) and/or the airbag module is/are arranged between the vehicle roof (56) and the vehicle roof lining (58) in the area of an upper windscreen rim, wherein the module cover (40) and/or the airbag module is/are formed so that, upon release of the vehicle safety system, an airbag (10) can be deployed and inflated along the windscreen (59).

16. The module cover according to claim 1, wherein the elongate clearance portion is configured over an entire width of the module cover panel.

17. A module cover (40) for an airbag (10) and/or an airbag module for being arranged beneath a vehicle roof (56), in the area of an upper windscreen rim, the module cover (40) comprising a module cover panel (41) including a rear side (42) pointing to the vehicle roof (56) during use and a front side (43) pointing away from the vehicle roof (56) during use, wherein the module cover panel (41) comprises an elongate clearance portion (44) in the form of an elongate indentation (45) formed in the front side (43) of the module cover panel (41), and a protective sheath (57) which is formed at least on the side of the module cover (40) opposed to the module cover panel (41) and together with the module cover panel (41) constitutes the module cover (40).

18. An airbag module for being arranged beneath a vehicle roof in an area of an upper windscreen rim, the airbag module comprising:
