SLIDING DEVICE FOR A VEHICLE SEAT PROVIDED WITH AN IMPROVED LOCKING ARRANGEMENT

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 (), one for each track of the sliding device, each including a plurality of locking pins () 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 () 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.
