A seat assembly includes a mounting plate and a base frame rotatable mounted on the mounting plate by a swivel mechanism for swiveling the seat assembly between forward-facing and rearward-facing configurations. A seat portion is operably coupled to the base frame and includes a front edge. The seat portion can be pivoted between use and upright non-use positions. The seat assembly includes a first rotational footprint when the seat portion is in the use position and a second rotational footprint that is less than the first rotational footprint when the seat portion is in the upright non-use position. The second rotational footprint is intended to accommodate swiveling of the seat assembly between the forward-facing and rearward-facing configurations within a vehicle interior.

A track assembly includes a first track having a first support extending from a first surface of the first track. The first support includes a first curved end. The track assembly includes a second track slidably coupled to the first track. The second track includes a second support extending from a second surface of the second track. The second support includes a second curved end. The first support and the second support are positioned such that the second curved end interfaces with the first curved end.

A stop (11, 11′), in particular an abutment for a longitudinal adjustment mechanism, includes a stop element (15, 15′) that can be placed in various positions. The stop element is configured to automatically lock into a retaining position.

A track assembly includes a first track having a first inner surface, a first support coupled to the first inner surface, a second track having a second inner surface, and a second support coupled to the second inner surface. The second track is slidably coupled to the first track. The first support has a first free end that extends from the first inner surface at a downward sloping angle. The second support has a second free end that extends from the second inner surface at an upward sloping angle. The first support and the second support are positioned such that the second free end is disposed above the first free end.

A rail assembly can include a track assembly, an elongate shaft mounted to the track assembly, and a carriage assembly received within the track assembly. The carriage assembly can include a slider bracket. The slider bracket includes a first ramp portion and a second ramp portion. The first and second ramp portions are disposed on opposite sides of the slider bracket. The first and second ramp portions each define a receiving aperture. The elongate shaft is received through the receiving apertures of the first and second ramp portions.

A seat rail pair for a vehicle seat is disclosed. The seat rail pair may have a lower rail and an upper rail. The upper rail may be moved relative to the lower rail via mutually engaged profiles. The lower rail may have a substantially C-shaped profile and the upper rail may have a substantially U-shaped profile. Roller members may be arranged between the upper rail and the lower rail to facilitate relative movement.

The present invention provides a seat-sliding apparatus for a vehicle. The seat-sliding apparatus includes a lower rail fixed to the vehicle, an upper rail, which is coupled to a seat and slides along the lower rail, a rail groove portion, which is formed in at least one surface of the lower rail and has therein a plurality of grooves, a tooth portion having teeth positioned between the grooves in the rail groove portion, a sloped portion, which is positioned at at least a portion of the rail groove portion and in which heights of the teeth of the tooth portion decrease toward a center of the rail groove portion from one end of the rail groove portion in a longitudinal direction, and a locking unit, which is positioned at the upper rail and is selectively engaged with the rail groove portion so as to hold the upper rail.

A slide rail for a vehicle seat, comprising first and second slidably mounted profiles and a latch. Each of the first and second profiles has a web and two side flanges. The side flanges of the second profile are extended further towards one another by two re-entrant troughs themselves extended further towards the web of the second profile by downward edges. The side flanges of the first profile are extended further away from each other by flaps which pass between the downward edges and the web of the second profile. The web of the second profile comprises rigid abutments arranged facing the downward edges, the flaps of the first profile passing between the abutments and the downward edges.

A rail assembly includes a track assembly with a retaining lip and a carriage assembly that is received within the track assembly. The carriage assembly includes a body portion, an exterior surface of the body portion, and a retaining bracket fastened to the exterior surface. The retaining bracket extends outwardly from the point at which the retaining bracket is fastened to the exterior surface. The retaining bracket defines a notch that receives the retaining lip of the track assembly.

A seat slide device includes a reinforcing member attached to a rear end part of an upper rail. The reinforcing member is higher in rigidity than the upper rail. The reinforcing member 7 includes: a reinforcing member body having a U-shaped cross section having a lower opening, and including: a reinforcing member top wall; and a pair of reinforcing member lateral walls; and a pair of reinforcing member bent wall parts each being bent outwardly from a lower end of a corresponding one of the reinforcing member lateral walls in a lateral direction of the reinforcing member, and extending upwardly between a corresponding lower rail outside lateral wall and a corresponding lower rail inside lateral wall.
