An armrest assembly for a vehicle seat, the assembly comprising an armrest, a support, and an intermediate portion, the armrest being movable in translation along a vertical direction relative to the support, the assembly further comprising a locking device for the armrest comprising: a first part having toothed elements, and a second part capable of coming into contact with the toothed elements of the first part, and wherein the second part is movable between a locking position in which the second part is in contact with the toothed elements of the first part and an unlocking position allowing movement in translation along the vertical direction of the armrest.

The present disclosure discloses a child safety seat and a side impact protection mechanism thereof, the side impact protection mechanism is provided at a backrest of the child safety seat and includes a side impact protection block and a self-locking structure. The side impact protection block is movably fitted to the backrest and has a folding position in which the side impact protection block is inwardly folded in the backrest and an unfolding position in which the side impact protection block is outwardly unfolded from the backrest. The self-locking structure automatically moves to a position that blocks the side impact protection block in the unfolding position from switching to the folding position when the side impact protection block is switched from the folding position to the unfolding position, the self-locking structure is fitted to the side impact protection block or the backrest, and the backrest and the side impact protection block shields the self-locking structure to block a release operation of the self-locking structure by an operator, so that the side impact protection block cannot be inwardly folded into the backrest after the first use, thereby effectively preventing the side impact protection block from being accidentally folded during the side impact to provide a side impact protection effect.

The embodiments described and claimed herein are improved vehicle access systems. In particular, one embodiment includes three compact, motorized mechanisms for pivoting a passenger seat toward a door opening, extending the passenger seat outside the door opening, lowering the passenger seat, and tilting the passenger seat to help the passenger stand. The first mechanism concurrently pivots the passenger seat and moves it sideways during the pivoting operation so that it is aligned with the door opening. The second mechanism extends the passenger seat outside the door opening. The third mechanism lowers the seat.

A lock mechanism for controlling a rotating component including an outer shaft attachable to a stationary component and having a slotted ring defining capture slots and an interior annular space, a control ring having a first end disposed in the annular space, an inner shaft attachable to a rotating component configured to rotate relative to the stationary component, and the inner shaft engaged with a second end of the control ring, a first collar rotatably disposed around the slotted ring, the first collar having a plurality of release recesses, and a plurality of first bearings respectively retained within the capture slots beneath the first collar. In a first rotational position of the first collar, the plurality of release recesses align with the capture slots to rotationally disengage the rotating and stationary components. In a second rotational position of the first collar, the plurality of release recesses misalign with the capture slots to rotationally engage the rotating and stationary components.

A vehicular locking device includes a bore having first and second ends. A gas generating device is proximate the first end. A piston is movable along an interior of the bore. The vehicular locking device includes first and second plates. The second plate includes an aperture. Activation of the gas generating device accelerates the piston through the aperture and the second plate preventing displacement of the second plate.

An actuator comprises a housing, a motor, a drive mechanism and a clutch coupled to the drive mechanism. The motor is mounted displaceably relative to the housing. A displacement of the motor relative to the housing is operative to actuate the clutch.

A detachable vehicle seat includes: a seat cushion including a seat latch for selectively securing the seat cushion to a vehicle body, and a seat control device for selectively unlatching the seat latch; a seatback pivotally attached to the seat cushion via a recliner device, the recliner device including a recliner control device configured to selectively cause the recliner device to be in a first state for locking the seatback in an upright position and a second state for locking the seatback in a stowage position; a first connecting element connecting the recliner device to the seat control device so that the seat latch can be unlatched only when the recliner device is in the second state; and a second connecting element connecting the seat latch to the recliner control device so that the recliner device can take the first state only when the seat latch is fully latched.

A track adjuster 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, and a second lockset configured that may be configured to selectively restrict movement of the second pair of tracks. The first lockset may be a first type of lockset and the second lockset may be a second type of lockset. The first lockset may include a positive engagement locking lockset. The second lockset may include a pawl-type lockset.

A passive self-adjusting seat assembly for a lawn maintenance vehicle having a frame. The passive self-adjusting seat assembly includes a base, a guide assembly attached to the base, and a platform assembly that is selectively movable or slidable relative to the guide assembly in order to maintain an operator in an upright or substantially vertical orientation as the lawn maintenance vehicle traverses uneven or sloped ground. The seat assembly further including a locking assembly for selectively locking the sliding or movement of the platform assembly relative to the guide assembly.

A vehicle proposed herein includes a swivel, a lock mechanism selectively locking and unlocking the swivel, a seat mounted on the swivel, a plurality of surface pressure sensors each disposed along an outer surface of the seat and detecting a pressure distribution within a predetermined area of the outer surface, and a controller configured to cause the lock mechanism to be unlocked based on a change in pressure distribution or a surface pressure that is detected by any of the plurality of surface pressure sensors.
