Abstract: A sliding device for a vehicle seat is provided. The sliding device includes a pair of parallel slideways, each of which comprises a lower rail, an upper rail slidably mounted to the lower rail and a latch for allowing/preventing a movement of the upper rail relative to the lower rail. A releasing member is provided for driving the latches to a position in which the upper rails are free to move relative to the lower rails. Each latch has a rear portion which is bent into a “U”-like shape and comprises a lower leg carrying latching elements configured to cooperate with corresponding latching elements provided in the lower rail and an upper leg configured to engage the releasing member. The design of the latches improves the reliability of the sliding device.

Abstract: A sliding device for a vehicle seat includes a pair of tracks, each having a lower rail and an upper rail, and a locking arrangement having a pair of locking assemblies, each including locking pins for locking a respective one of the upper rails to a respective one of the lower rails. The locking arrangement includes a releasing assembly for driving the locking pins of each of the locking assemblies to an unlocking configuration. The releasing assembly includes a releasing member and a pair of connecting members. The connecting members are each in a force transmission connection with the releasing member and with the locking pins of a respective one of the locking assemblies. The connecting members are entirely received within the tracks, and the releasing assembly is configured to convert rotational movement of the releasing member into linear movement of the locking pins of each of the locking assemblies.

Abstract: A sliding device for a vehicle seat is provided with a pair of tracks and an improved releasing assembly. The sliding device comprises a pair of locking assemblies, one for each track, each including a plurality of locking pins for locking upper rails of the tracks to lower rails of the tracks. The sliding device further includes a releasing assembly for driving the locking pins to an unlocking configuration for adjusting the position of the vehicle seat. The releasing assembly comprises a releasing member having a pair of substantially parallel arms pivotally connected to the tracks, a crossbar extending transversely to the tracks and provided at each end with an engaging assembly for engaging the locking pins of the respective locking assembly, and a pair of connecting members configured to convert a rotational movement of end portions of the arms into a translational movement of the crossbar.

Abstract: The present invention relates to a sliding device (1) for a vehicle seat. The sliding device comprises a pair of parallel slideways (3a, 3b), each of which comprises a lower rail (5a, 5b), an upper rail (7a, 7b) slidably mounted to the lower rail and a latch (21a, 21b) for allowing/preventing a movement of the upper rail relative to the lower rail; a releasing member (29) is provided for driving said latches to a position in which the upper rails are free to move relative to the lower rails. According to the invention, each latch (21a, 21b) comprises a rear portion which is bent into a “U”-like shape and comprises a lower leg carrying latching elements (37a, 37b) configured to cooperate with corresponding latching elements (41a, 41b) provided in the lower rail and an upper leg configured to engage the releasing member (29). The design of the latches of the sliding device of the invention allows to improve the reliability of said sliding device.

Abstract: A sliding device for a vehicle seat is provided with an improved locking arrangement. The locking arrangement includes a pair of locking assemblies, each including one or more locking pins suitable for locking upper rails of the seat tracks to respective lower rails. The locking arrangement also includes a releasing assembly suitable for driving the locking pins to an unlocking configuration and comprising a releasing member and a pair of connecting members, which are in a force transmission connection with the releasing member and with the locking pins of a respective locking assembly. The connecting members are entirely received within the respective tracks, and the releasing assembly is configured to convert a rotational movement of the releasing member into a linear movement of the locking pins of the locking assemblies.

Abstract: A discontinuous recliner for a vehicle seat is provided. The discontinuous recliner comprises one or more locking pawls and a single actuating element which is configured to drive the locking pawl(s) both from the locking position to the unlocking position and from the unlocking position to the locking position. Thanks to the provision of the single actuating element, the overall number of components of the discontinuous recliner is significantly reduced. This allows to obtain a discontinuous recliner which is lighter, easier to be assembled and more reliable.

Abstract: The present invention relates to a reclining device (1) for a vehicle seat of the kind comprising a first plate carrying an internal gear (5) and a second plate carrying an external gear (11) configured to cooperate with the internal gear. The reclining device includes a first and second wedge elements (17a, 17b) for exerting a wedge effect and preventing accidental, undesired rotation of the external and internal gears relative to each other. The reclining device (1) further comprises a lock spring (21). According to the invention the lock spring (21) comprises a wedge engaging element (35) that can be brought to abut and engage a lock spring abutment surface (37a, 37b) of a wedge element. Thanks to this arrangement, the lock spring directly interacts with the wedge elements and directly restricts self-rotation of said wedge elements, which avoids any loss of force and function between said lock spring and said wedge elements.

Abstract: The present invention relates to a sliding device for a vehicle seat provided with an improved releasing assembly. Said sliding device 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 sliding device further includes a releasing assembly for driving said locking pins to an unlocking configuration for adjusting the position of the vehicle seat.
