A vehicle seating assembly comprises a lift mechanism disposed at a forward portion of a seat and a latch assembly disposed at a rearward portion of the seat and rotatably coupled to the seat. A mechanical link has a first end rotatably coupled to the forward portion of the seat and a second end rotatably coupled to the latch assembly. The vehicle seating assembly is movable between a first position and a second position, wherein the latch assembly is positionable in a latched position or an unlatched position relative to a mount assembly. The mechanical link is disposed in an initial position when the seating assembly is in the first position, and the mechanical link is disposed in a final position when the seating assembly is in the second position.

A vehicle seating assembly is provided that includes a seat rotatable about an axis of rotation disposed at a front of the seat between a sitting position and a standing position, a latch assembly rotatably coupled to the rear of the seat and releasably coupled to a track assembly disposed below the seat, wherein if the seat is in a sitting position, the latch assembly is in a locked position relative to the track assembly, and wherein if the seat is in a standing position, the latch assembly is in an unlocked position relative to the track assembly, and a connecting bar extending through the latch assembly, wherein the latch assembly is rotatable around the connecting bar as the seat moves between the sitting position and the standing position.

Actuating drive having: a transmission including a housing, a transmission gear engaging a driveshaft, a bearing, and a spindle rotatable about a rotational axis and extending through an inner thread of the transmission gear and outlets of the housing. The housing has a cylindrical bore receiving the bearing and defining a cylinder axis. The bearing is delimited by a three-dimensional area, the largest cross-sectional area of which is circular and, when viewed in the direction of the cylinder axis, perpendicular to the cylinder axis in the intersection of the cylinder axis and the rotational axis. The cross-sectional area decreases with increasing distance from the intersection in both directions of the cylinder axis. The bearing has two bearing shells, each having a bearing opening centered relative to the rotational axis, which the spindle passes through, and in which the transmission gear is rotatably mounted.

An electric ground slide rail transmission system disclosed in the present invention includes a left rail assembly, a right rail assembly, a driving rail assembly, and a slide rail connection frame. The driving rail assembly includes a lower rail assembly, a transmission box support slidably disposed on the lower rail assembly, a transmission assembly mounted in the transmission box support, an output gear configured to be driven by the transmission assembly, and a driving motor mounted to the transmission box support. The driving motor is configured to drive the transmission assembly to operate, the transmission assembly is configured to drive the output gear to rotate, the output gear is meshed with a rack disposed in the lower rail assembly to drive the transmission box support, and the transmission box support drives, by using the slide rail connection frame assembly, the seat to be adjusted frontward and rearward along the left rail assembly and the right rail assembly. The present invention provides a transmission system integrated with gears and racks, so as to implement a stable, beautiful, and low-cost electric ground slide rail transmission system.

The present invention relates to an aircraft seat comprising: a guide rail (26); a rack (34); an actuator (30) provided with a gear (31); at least one connection portion (35) providing a mechanical connection between the guide rail (26) and the rack (34),
characterized in that the connection portion (35) included a zone (36) of mechanical weakness and in that a first bearing element (37) and a second bearing element (38) are disposed on either side of the rack (34), such that, if the deformation of the seat generates a movement of the gear (31), said gear (31) or the corresponding shaft (32) comes into abutment against one of the bearing elements (37, 38) and in this way deforms the connection portion (35) along the zone (36) of mechanical weakness.

The present invention relates to techniques for activating a lock in a vehicle. Said techniques discuss capturing an image of an interior of the vehicle, the image comprising an occupant on a seat of the vehicle, detecting a weight value of the occupant on a respective seat of the vehicle, processing the image for determining whether the occupant is a human or an object or an animal. It further discusses in response to the determination that the occupant is the human processing the image for determining a parameter of the human, and activating a lock based on the parameter, or the weight value and the parameter.

The present disclosure relates to an adjustment device for a vehicle seat comprising adjusters adjustable in relation to one another, where on the first adjuster a toothed rack with an interlocking is hinged, and on the second adjuster a pinion is pivoted, the interlocking engaging with the pinion for adjusting the toothed rack and for moving the two adjusters in relation to one another, where, further, a toothed rack blocking element is affixed to the second adjuster, and the toothed rack, when adjusted, runs between the toothed rack blocking element and the pinion.

A seat assembly for use in an automotive vehicle includes a seat back pivotally coupled to a seat cushion and at least one link pivotally coupled between the seat cushion and a seat base. A detent assembly is rotatably coupled to the seat base, the detent assembly actuatable between a use condition for operatively coupling the at least one link and the detent assembly, and an override condition for decoupling the at least one link and the detent assembly. A linkage motor is operatively engaged with the detent assembly for pivoting the at least one link to move the seat assembly between a plurality of positions. Actuation of the detent assembly from the use condition to the override condition allows for manual pivoting of the at least one link to move the seat assembly between the plurality of positions in situations where the linkage motor is unable to be actuated.

A vehicle seat including: a seat body configured to seat an occupant; a pressing mechanism that is provided at the seat body and is switchable between a pressing state, in which the pressing mechanism presses against the pelvis of a seated occupant, and a non-pressing state, in which the pressing mechanism does not press against the pelvis of a seated occupant; and a control section configured to control the pressing mechanism, in a state in which an occupant is sitting on the seat body, so as to alternate repeatedly between the pressing state and the non-pressing state.
