Abstract: Described herein is a device for sending down seat backrests in vehicles. The backrests are manually mobile between two operative positions. The device is provided with: an anchoring plate and a supporting plate hinged to one another and fixed, respectively, to a seat-cushion frame and to the backrest; and a blocking plate, set between the anchoring plate and the supporting plate. The blocking plate is manually mobile against the elastic action of a spring fixed to the anchoring plate and is provided, together with the anchoring plate itself, with respective guide slots engaged by a pin fixed to the supporting plate and mobile between two blocking seats made at the opposite ends of the guide slot of the blocking plate, in positions staggered with respect to the guide slot of the blocking plate itself.

Abstract: Described herein is a device (1) for sending down seat backrests (2) in vehicles, the backrests (2) being manually mobile between two operative positions, and the device (1) being provided with: an anchoring plate (10) and a supporting plate (20) hinged to one another and fixed, respectively, to a seat-cushion frame (100) and to the backrest (2); and a blocking plate (30), set between the anchoring plate (10) and the supporting plate (20); the blocking plate (30) being manually mobile against the elastic action of a spring (50) fixed to the anchoring plate (10) and being provided, together with the anchoring plate (10) itself, with respective guide slots (14, 33) engaged by a pin (22) fixed to the supporting plate (20) and mobile between two blocking seats (34a, 34b) made at the opposite ends of the guide slot (33) of the blocking plate (30), in positions staggered with respect to the guide slot (33) of the blocking plate (30) itself.

Abstract: Described herein is a supporting unit (1) for supporting an external spare wheel (2) underneath the floor panel (3) of a motor vehicle, the unit (1) having a box-section supporting bracket (4) fixed to the floor panel (3), and a cable (6) for transmitting motion passing through the bracket (4) and provided with a first end (7) fixed to a bell (5), which can be coupled to the wheel (2), and with a second end (8) fixed to a device for recovery of the cable (6) itself; a safety assembly (35) is arranged inside the bracket (4) and is set between the first end (7) and the bell (5) to secure the bell (5) itself in a recovery position in the event of failure of the cable (6) for transmitting motion.

Abstract: Described herein is a supporting unit (1) for an external spare wheel (2), designed to support the spare wheel (2) underneath the floor panel (3) of a motor vehicle, the unit (1) being provided with a box-section bracket (4) anchored to the floor panel (3) and a bell (5), which can be fitted to the spare wheel (2) and can be moved with respect to the bracket (4) away from and towards a recovery position, in which the bell (5) is set up against the bracket (4); an anti-sticking device (40) is associated to the box-section bracket (4) to prevent any sticking of the bell (5) and of a respective cable for transmitting motion (6) and is formed by an elastic compression element (41) set between the bell (5) and the supporting bracket (4), and a seal element (42) associated to the bell (5) for co-operating with the box-section bracket (4).
