Provided is a sliding device for a vehicle seat. The device includes a fixed rail, a movable rail, a lock portion, an operating lever, a first locking protrusion, and a lock lever. When a first contact surface among side faces of the first locking protrusion and a second contact surface among side faces of a second locking protrusion of the lock lever are in contact with each other, the operating lever is retained in one of a first position or a second position, and when a protruding-direction end of the first locking protrusion and a protruding-direction end of the second locking protrusion are in contact with each other, the operating lever is retained in the other of the first position or the second position.

A vehicle seat sliding apparatus includes a lower rail, an upper rail, a slide-lock mechanism that pivots the lock member to a slide-lock position and holds the upper rail in a slide-lock state, and a slide-lock cancellation unit moved by operation of an operation member in a longitudinal direction of the upper rail to cancel an action of the slide-lock mechanism. The slide-lock cancellation unit includes a drive unit and an inclined surface arranged in the drive unit. The drive unit is supported by the upper rail so as to be slidable in the longitudinal direction of the upper rail. Operation of the operation member slides the drive unit. The inclined surface pivots the lock member to a slide-lock cancellation position when sliding.

A shaft housing hole (27) has a shaft insertion hole (31) into which the rotating shaft section (45) of an engagement member (40) is inserted. Also, the shaft housing hole (27) has slits (32, 34) extending from the lower end of the shaft insertion hole (31) along the side surface of the shaft insertion hole (31) toward an upper connection wall section (21). The upper side wall section (22) of an upper rail (20) has shaft restriction sections (33, 35) formed by the shaft housing hole (27). The shaft restriction sections (33, 35) have front ends (33b, 35b) with which the side surfaces of the rotating shaft section (45) are in contact.

A vehicle slide rail device including: a memory mechanism which includes a memory member configured to define a default seat position by engagement; a release operation mechanism which is configured to release a lock mechanism from a locked state and slide together with the memory member in a slide direction by removing the memory member from a state of defining the default seat position; a memory operation mechanism which is configured to release the lock mechanism from the locked state while leaving the memory member in the state of defining the default seat position; a cancel mechanism which is pressed against the memory member to cancel the releasing of the lock mechanism by the memory operation mechanism and return the lock mechanism to the locked state when the seat position is returned to the default seat position defined while an operated state of a memory operation member is maintained.

A track assembly includes a first pair of tracks, a first lockset that may be configured to selectively restrict movement of the first pair of tracks, a second pair of tracks, a second lockset that may be configured to selectively restrict movement of the second pair of tracks, and a cross member that may be connected between the first pair of tracks and the second pair of tracks. The cross member may be configured to actuate the first lockset and the second lockset. The cross member may include a first section and a second section. The first section and the second section may be configured to rotate relative to each other.

[Summary] A mower unit includes an idler pulley unit and a single belt routed around an output pulley of a drive source, the idler pulley unit and a plurality of blade pulleys. The idler pulley unit includes a first idler pulley, a second idler pulley and a tension idler pulley. A pulley height of the idler pulley unit is set higher than a pulley height of the blade pulleys, and a forward belt portion from the output pulley and a reverse belt portion to the output pulley extend to pass over and above the blade belt portion.

A vehicle seating system includes a latch having multiple teeth configured to engage respective windows within a rail to selectively block movement of a vehicle seat relative to the rail. The latch includes a first tooth and a second tooth longitudinally separated from one another. The first tooth includes an inner surface configured to contact a longitudinal end of a first window while the first tooth is engaged with the first window to block movement of the latch relative to the rail along a first longitudinal direction, and the second tooth includes an inner surface configured to contact a longitudinal end of a second window while the second tooth is engaged with the second window to block movement of the latch relative to the rail along a second longitudinal direction, opposite the first longitudinal direction.

A seat slide device includes: a first rail which extends in a longitudinal direction; a second rail which extends in the longitudinal direction and is joined to the first rail to be capable of relative movement in the longitudinal direction; lock holes which form the first rail, are open in a portion facing the second rail, are provided to extend such that one end in a short direction of the first rail forms an opening portion, another end forms a base portion including a base wall, and which are disposed at an equal interval in the longitudinal direction; and a lock lever which is joined to the second rail in a state of being capable of reciprocal movement in the short direction and is provided integrally with engaging protrusions capable of entering and exiting any of the lock holes in accordance with the reciprocal movement.

A seat adjuster assembly including a handle, a first track assembly and a second track assembly. The first track assembly includes a first track defining an interior and a second track moveably mounted relative to the first track. A first trigger is pivotally mounted on a first trigger housing and connects to the handle. The first trigger is movable between an unlocked position permitting movement between the first and second tracks, and a locked position. The second track assembly includes a third track defining an interior and a fourth track moveably mounted relative to the third track. A second trigger is pivotally mounted on a second trigger housing and connects to the handle. The second trigger is movable between an unlocked position permitting movement between the third and fourth tracks, and a locked position.

A vehicular seat slide device includes a lower rail, an upper rail 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, 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 by being locked at a peripheral edge of the locking hole due to recovery of the elastic deformation.
