Abstract: A slide locking apparatus has: a first locking piece having a narrow width locking hook section, a third locking piece having a broad width locking hook section and a second locking hook having an intermediate width locking hook section, which are held on an upper aril; and first to third locking piece accommodating holes which have width corresponding to the widths of the respective locking hook sections of the first locking piece to the third locking piece, and which are provided in a lower rail. The first locking piece accommodating hole is disposed on a frontmost end, the second locking piece accommodating hole is disposed to the rear side of the first locking piece accommodating hole, and the third locking piece accommodating holes are disposed to the rear side of the second locking piece accommodating hole.

Abstract: A seat slide locking apparatus comprises a lower rail provided with a plurality of locking holes, and a plurality of locking pieces provided on the lower rail. The locking pieces include a first locking piece 4a having a broad width inserting section 46 and a second locking piece 4b having a narrow width inserting section 47, and are held by a holding member which has a holding hole 66. The holding hole 66 includes a broad width section 66a into which the broad width inserting section 46 is inserted and a narrow width section 66b into which the narrow width inserting section 47 is inserted.

Abstract: A slide locking apparatus for a seat includes a first locking section with plural first locking pieces and at least one second locking section group with forward, intermediate, and rear second locking sections. When at least one of the first locking pieces locks with one of the second locking sections, another first locking piece locks with another second locking section. A first lock inhibiting section inhibits the forward second locking section from engaging any of the locking pieces when a rearwardmost locking piece is forward of a position where the rearwardmost locking piece coincides with the intermediate locking section. A second inhibiting section inhibits the rear second locking section from locking with any of the locking pieces when the forward locking piece is rearward of the intermediate locking section.

Abstract: Disclosed is a slide locking mechanism for a seat, which comprises at least five locking pieces, a plurality of first latch portions and a plurality of second latch portions. An opening width of a hole of each of the first latch portions in a longitudinal direction of a lower rail is equal to a width of each of the locking pieces in the longitudinal direction, and an opening width of a hole of each of the second latch portions in the longitudinal direction is greater than the opening width of each of the holes of the first latch portions. The first latch portions and the second latch portions are alternately arranged along the longitudinal direction.

Abstract: An automobile seat includes a swinging motion restraint mechanism for restraining a swinging motion of a sub-frame relative to side frames. The swinging motion restraint mechanism includes a swing axis mounted on the sub-frame, a swinging motion restraint member rotatably mounted on one of the side frames and having a first contact portion and a second contact portion, both of which are brought into contact with the swing axis one at a time, and an elastic member for biasing the swinging motion restraint member toward the swing axis.
