Patent claims

1 . Combiner positioning unit (10) for a head-up display system for usage in vehicles, comprising

a housing (14),

a combiner (12) with a combiner support (16), wherein the combiner support (16) is pivotably arranged around a pivot axis (18) between a folded-in storage position and a folded-out operating position in the housing (14), and

an actuating element (20) for releasing the combiner support (16) from the storage position, characterized in that

the combiner support (16) comprises a first locking element (22) for engaging with a corresponding second locking element (24) of the housing (14), and in the storage position the first locking element (22) is engaged with the second locking element (24), and

by operating the actuating element (20), the combiner support (16) is at least partially moved in axial direction of the pivot axis (18) against a spring force of a first spring element (26), disengaging the connection of the first locking element (22) and the second locking element (24), and a spring force of a second spring element (32) connected to the combiner support (16) pivots the combiner (12) around the pivot axis (18) into the operating position.

2. Combiner positioning unit according to claim 1 , characterized in that the first spring element (26) is arranged on the pivot axis (18) between the combiner support (16) and the housing (14).

3. Combiner positioning unit according to claim 1 or 2, characterized in that the

second spring element (32) is connected to the combiner support (16) in a direction perpendicular to the pivot axis (18) of the combiner support (16).

4. Combiner positioning unit according to one of the claims 1 to 3, characterized in that the second spring element (32) is pre-loaded when the combiner (12) is in storage position.

5. Combiner positioning unit according to one of the claims 1 to 4, characterized in that the actuating element (20) comprises

an actuating button (36) guided in a guiding hole (38) of the housing (14) and an actuating wheel (40) rotatably arranged in the housing (14) and in operating connection with the actuating button (36), so that

the actuating wheel (40) is at least partially rotatable around its rotational axis (42) due to a translational movement of the actuating button (36), wherein the actuating wheel (40) is in operating connection with the combiner support (16), so that due to the rotational movement of the actuating wheel (40) the combiner support (16) is at least partially moved in axial direction of the pivot axis (18) against the spring force of the first spring element (26) disengaging the connection of the first locking element (22) and the second locking element (24).

6. Combiner positioning unit according to claim 5, characterized in that the actuating button (36) is operable against a spring force of a third spring element (44), preferably arranged between the housing (14) and a button head of the actuating button (36).

7. Combiner positioning unit according to claim 5 or 6, characterized in that the

operating connection between the actuating button (36) and the actuating wheel (40) is a toothed structure.

8. Combiner positioning unit according to claim 7, characterized in that the toothed structure of the actuating wheel (40) is arranged on an outer periphery of a first projection (46) of the actuating wheel (40) extending in radial direction.

9. Combiner positioning unit according to one of the claims 5 to 8, characterized in that the actuating wheel (40) comprises a second projection (48) extending in radial direction comprising an actuating cam (50) for operating with the combiner support (16), wherein the actuating cam (50) extends in axial direction of the actuating wheel (40).

10. Combiner positioning unit according to one of the claims 5 to 9, characterized in that the actuating wheel (40) is in operating connection with the housing (14) so that due to an rotational movement of the actuating wheel (40), the actuating wheel (40) is at least partially moved in axial direction of the rotational axis (42), wherein due to the axial movement of the actuating wheel (40) the combiner support (16) is at least partially moved in axial direction of the pivot axis (18) against the spring force of the first spring element (26) disengaging the connection of the first locking element (22) and the second locking element (24).

1 1 . Combiner positioning unit according to one of the claims 5 to 10, characterized in that the actuating wheel (40) comprises a front side (52) arranged in direction of the rotational axis (42) of the actuating wheel (40) facing the housing (14), wherein at least one first ramp element (54) comprising an inclined first sliding surface (56) with respect to the front side (52) of the actuating wheel (40) is arranged on the front side (52), and the housing (14) comprises on its surface (58) facing the actuating wheel (40) at least one corresponding second ramp element (60) comprising an inclined second sliding surface (62), wherein in an rotational movement of the actuating wheel (40) relative to the housing (14), the inclined first sliding surface (56) slides at least partially along the inclined second sliding surface (62) moving the actuating wheel (40) in axial direction of the rotational axis (42).

12. Combiner positioning unit according to claims 10 or 1 1 , wherein the actuating wheel (40) is at least partially moveable in axial direction of the rotational axis (42) against a spring force of a fourth spring element (64), wherein the fourth spring element (64) is preferably arranged in longitudinal direction of the rotational axis (42) of the actuating wheel (40).

13. Combiner positioning unit according to one of the previous claims, characterized in that the first locking element (22) is a locking pin and the second locking element (24) is an engagement hole in the housing (14).

14. Combiner positioning unit according to claim 13, characterized in that the locking pin and/or the housing (14) surrounding the engagement hole comprises an inclined structure formed and arranged in such a manner that when the combiner (12) is manually pivoted from operating position in storage position the locking pin slides along the inclined structure shifting the combiner support (16) in axially direction against the spring force of the first spring element (26) and when the locking pin is aligned with the engagement hole, the spring force of the first spring element (26) shifts the combiner support 16 in axial direction for engaging the locking pin in the engagement hole.
