Sliding device for a vehicle seat provided with an improved locking arrangement

A sliding device for a vehicle seat, comprising:

• a pair of parallel tracks, each comprising a lower rail and an upper rail, each of the upper rail being constrained to a respective lower rail, but slidable relative to the lower rail,
• wherein the upper rails and the lower ails have respective longitudinal axes,
• wherein the lower rails are provided with a plurality of apertures arranged along the longitudinal axes of the lower rails,
• wherein the sliding device is provided with a locking arrangement including two locking assemblies, one for each of the tracks,
• wherein each locking assembly comprises one or more locking pins, which are configured to penetrate into corresponding apertures of the respective lower rail,
• wherein the locking arrangement further comprises a releasing assembly for moving the locking pins from a locking configuration to an unlocking configuration,
• wherein the releasing assembly comprises a releasing member and a pair of connecting members, one for each locking assembly, each connecting member being in a force transmission connection with the releasing member and with the locking pins of the respective locking assembly, such that, when a force is applied to the releasing member, the force is transmitted from the releasing member to the connecting members, and from the connecting members to the locking pins of the respective locking assembly,. thereby driving the locking pins from their locking configuration to their unlocking configuration,
• wherein the connecting members are configured to drive the locking pins along a substantially linear path from the locking configuration to the unlocking configuration,
• wherein each connecting member comprises an engaging plate, arranged between the respective upper and lower rails and provided with a window, through which the locking pins are configured to pass,
• wherein each engaging plate is configured to slide along a substantially linear path to drive the locking pins of the respective locking assembly along a substantially linear path from the locking configuration to the unlocking configuration,
• wherein each of the locking pins is provided with at least one transversely projecting peg,
• wherein the width of the window is larger than the diameter of the locking pins, but smaller than the sum of the diameter of the locking pins and of the length of the at least one transversely projecting peg, and
• wherein each of the at least one transversely projecting peg is arranged on a body of one of the locking pins so that the at least one transversely projecting peg is substantially in abutment against the respective engaging plate when the locking pin on which the at least one transversely peg is arranged is completely inserted into one of the apertures of the lower rails.
