Abstract: The present invention relates to a sliding device for a vehicle seat provided with an improved locking arrangement. Said locking arrangement comprises a pair of locking assemblies (101a, 101b; 201a, 201b), one for each track of the sliding device, each including a plurality of locking pins (105a, 105b; 203a, 203b) suitable for locking the upper rails of the tracks to the respective lower rails. Said locking arrangement further includes a releasing assembly for driving said locking pins to an unlocking configuration for adjusting the position of the vehicle seat. According to the invention, for any selected positions of the vehicle seat, all the locking pins (105a, 105b; 203a, 203b) of the locking assemblies simultaneously or quasi-simultaneously penetrate into corresponding apertures of the lower rails. Therefore, the invention advantageously allows to optimize the locking effect of the locking arrangement, as all the locking pins give their contribution to said locking effect.

Abstract: A sliding device for a vehicle seat is provided with a locking arrangement including a pair of locking assemblies, one for each track of the sliding device. Each track has an upper rail and a lower rail, and each of the locking assemblies includes a plurality of locking pins for locking one of the upper rails to a respective one of the lower rails. The locking arrangement further includes a releasing assembly for driving the locking pins of the locking assemblies to an unlocking configuration. The releasing assembly comprises a releasing member and a pair of connecting members, each of which is connected in a force transmission connection with the releasing member and the plurality of locking pins of one of the locking assemblies. Each of the connecting members is entirely received inside a respective one of the tracks, whereby the locking arrangement has a very compact design.

Abstract: The present invention relates to a sliding device for a vehicle seat provided with an improved locking arrangement. Said locking arrangement comprises a pair of locking assemblies (1a, 1b), one for each track of the sliding device, each including a plurality of locking pins (3a, 3b) suitable for locking the upper rails of the tracks to the respective lower rails. Said locking arrangement further includes a releasing assembly for driving said locking pins to an unlocking configuration for adjusting the position of the vehicle seat. Said releasing assembly comprises a releasing member and a pair of connecting members (7a, 7b), which are in a force transmission connection with the releasing member, on one hand, and with the locking pins (3a, 3b) of a respective locking assembly, on the other hand. According to the invention, such connecting members (7a, 7b) are configured to slide along a substantially linear path and to consequently drive the locking pins along a substantially linear path.

Abstract: The present invention relates to a sliding device (100) for a vehicle seat, comprising a pair sliding tracks (10), each including a lower rail (20) and an upper rail (30), which allow to obtain an improved stability and to reduce the sliding efforts when the upper rails slide relative to the lower rails. Each upper rail is constrained to a respective lower rail and is free to slide relative thereto, balls (70) are arranged between said upper rail and said lower rail, and said upper and lower rails are shaped so as to define a lower and an upper ball guides (72, 74) on each side thereof. The design of said upper and lower rails at said lower and upper ball guides (72, 74) is such that efforts during relative sliding movements of the rails are reduced, while enhancing stability of the rails and preventing deformations thereof.

Abstract: The present invention relates to a sliding device for a vehicle seat provided with an improved locking arrangement. Said locking arrangement comprises a pair of locking assemblies (1a, 1b), one for each track of the sliding device, each including a plurality of locking pins (5a, 5b) suitable for locking the upper rails of the tracks to the respective lower rails. Said locking arrangement further includes a releasing assembly for driving said locking pins to an unlocking configuration for adjusting the position of the vehicle seat. Said releasing assembly comprises a releasing member (9) and a pair of connecting members (11a, 11b), which are in a force transmission connection with the releasing member (9), on one hand, and with the locking pins (5a, 5b) of a respective locking assembly, on the other hand. According to the invention, such connecting members (11a, 11b) are entirely received inside the respective tracks.
