摘要:
A slide rail assembly (20) includes at least two slide rails (22, 26) . One of the two slide rails (22, 26) includes a pair of walls (28a, 28b) and a middle wall (30) connected between the pair of walls (28a, 28b). The middle wall (30) of the slide rail is arranged with a predetermined part (52) bent relative to the middle wall (30), and the predetermined part (52) is formed with a ball groove (40).

A position detecting device for a vehicle and a seat position detecting device which are compact in structure and low in production cost are proposed, in which the absolute position from the reference point can be always detected. The position detecting device 14 for a vehicle for detecting a position of a mobile object 3 for the vehicle which is moved by a driving force of a rotating driving source 70a includes a deceleration device 50 having a two-stage hypo-cycloid mechanism 56, 57, 58 and 59 decelerating the rotation amount of a rotation shaft rotated plural revolutions to one revolution or less by the driving source 70a upon the mobile object 3 being moved and a rotation sensor 51 detecting a rotation output from the deceleration device as an absolute angle, wherein a position of the mobile object is detected based on the absolute angle detected by the rotation sensor.

The invention relates to a longitudinal adjuster (3) for a vehicle seat (1), comprising at least one lower rail (9), at least one upper rail (11), which can be moved in relation to the lower rail (9) in the longitudinal direction (x), and at least one locking unit (13) for locking the upper rail (11) in relation to the lower rail (9). According to the invention, the locking unit (13) comprises at least two locking elements (VR), which, in order to lock the upper rail (11) and the lower rail (9), engage in the upper rail and the lower rail in a blocking manner in steps in such a way that at least one of the locking elements (VR) pre-locks the upper rail (11) and the lower rail (9) with play in relation to each other in a pre-locking step and that at least one of the locking elements (VR) locks the upper rail (11) and the lower rail (9) to each other without play in a locking step. The invention further relates to a vehicle seat (1) comprising such a longitudinal adjuster (3).

A power seat apparatus for a vehicle (12) includes a lower rail (21) provided at a vehicle floor, an upper rail (22) slidably supported by the lower rail and holding a seat for the vehicle, a screw member (23) arranged between the lower rail and the upper rail and extending in a direction where the upper rail is slidable, a feed nut member (24) meshed with the screw member, a retention member fixed to the upper rail, a holding member held by the retention member, a drive unit (25) transmitting a rotation drive force to one of the screw member and the feed nut member, and first and second cut-and-lifted portions (60,61) formed at first and second longitudinal walls of the upper rail respectively, the cut-and-lifted portions making contact with the holding member when a load is applied to one of the screw member and the feed nut member in an axial direction thereof to distribute the load to the upper rail, the cut-and lifted portions being formed by bending portions of the first and second longitudinal walls.

A vehicular seat slide device includes a lower rail, an upper rail provided to be movable relative to the lower rail along a long-side direction of the lower rail and supporting a seat above, a lock lever supported by the upper rail and configured to restrict the relative movement of the upper rail by engaging with the lower rail. The vehicular seat slide device includes a spring attached to the upper rail and biasing in such a manner that the lock lever engages with the lower rail. The spring includes a locking portion inserted in a locking hole provided at an upper edge of the upper rail and opening to a side surface of the upper rail, the locking portion is insertable into the locking hole by elastically deforming the spring body towards an inner side relative to the locking hole, the locking portion is restricted from being detached from the locking hole in an insertion direction by being locked at a peripheral edge of the locking hole due to recovery of the elastic deformation.
摘要:
In a case where an engagement member (20) is assembled on an upper rail (40), a second rotary shaft portion (26L) is inserted to a shaft receiving bore (47) of a first side wall portion (44a) from an inner side of an upper rail (40). After the insertion, the engagement member (20) is rotated so that the second rotary shaft portion (26L) is inserted to the shaft receiving bore (47) of the second side wall portion (44b). At this time, because a shaft allowable length (L2) is specified to be greater than a shaft maximum rotation length (L4), an interruption of an insertion of the rotary shaft portion (26) because of a contact of the second rotary shaft portion (26L) with an edge portion of the shaft receiving bore (47) at the second side wall portion (44b) is restrained.
