A seat assembly includes a first frame with a guide member extending outwardly along a first axis. A second frame has a second guide member extending outwardly. One of the first and second guide members is received in translation along the first axis by the other of the first and second guide members to connect the second frame to the first frame. A first locking element is engaged to couple the first frame to the second frame and limit translational movement of the first frame relative to the second frame. A method of assembling a seat assembly is also provided.

A back pad assembly for a material handling vehicle is provided that includes a back pad, a framework, and a mounting frame. The back pad includes a center portion, a first side portion, and a second side portion. The first side portion defines a first curved profile, and the second side portion defines a second curved profile. The first curved profile and the second curved profile are arranged on laterally-opposing sides of the center portion. The framework includes a first mounting bar and a second mounting bar. The framework is coupled to the back pad. The first and second mounting bars are adjustably supported by the mounting frame to enable the back pad to be selectively mounted at varying heights along the mounting frame.

Proposed is a support driver for a seat and a support assembly including the same. The support driver is configured to operate within a limited space while supporting an occupant comfortably and safely. The support assembly has a structure in which the links push the central portion of the cushion in close contact therewith while remaining in intersection with each other. Advantageously, the links are able to push the cushion with a minimum amount of power within a limited space.

A child safety seat includes a seat portion, a backrest assembly connected with the seat portion and including a first and a second portion slidably connected with each other and a third portion slidably connected with the second portion, and a backrest adjusting system carried with the backrest assembly and configured to provide a first stage of height adjustment where the first and second portions are locked with each other and the third portion is movable relative to the first and second portions for adjustment, and a second stage of height adjustment where the second portion is locked with the third portion and unlocked from the first portion so that the second portion and the third portion are movable in unison relative to the first portion for adjustment.

A vehicle-mounted seat device includes an SB main frame, a backrest, an SB subframe, and one or more front-back position regulation mechanisms for regulating the position of the SB subframe in the front-back direction relative to the SB main frame. Each front-back position regulation mechanism includes a front restraining bracket secured relative to the SB main frame, a rear restraining bracket secured on the SB subframe, and a front-back wire strung between the front and rear restraining brackets. The rear restraining bracket is deformed such that its front end portion is displaced rearward relative to its end portion upon input of a load greater than a predetermined load. A maximum pulling load of the front-back wire is greater than a load that causes initial deformation of the rear restraining bracket.

A child safety seat includes a backrest assembly including a first, a second, and a third portion slidably connected with one another, and a backrest adjusting system carried with the backrest assembly and configured to provide a first stage of height adjustment where the first and second portions are locked with each other and the third portion is movable relative to the first and second portions for adjustment, and a second stage of height adjustment where the second portion is locked with the third portion so that the second and third portions are movable in unison relative to the first portion for adjustment. The third portion carries an adjustment latch that engages with the second portion for locking the third portion in position in the first stage of height adjustment and engages with the first portion for locking the third portion in position in the second stage of height adjustment.

A kayak seat is provided that includes a seat base, and a seat pan supported by, and attached to, the seat base. The seat pan is made from a flexible material such that the seat pan is configured to be adjustable. The seat pan is configured to support the pelvis and thighs of a user seated in the seat pan. A seat back is attached to the seat base. A first adjustment mechanism is configured to adjust a position of the seat pan from a single point of adjustment. A second adjustment mechanism is configured to adjust a position of the seat back.

The vehicle seat includes: an adjustment position selecting means for selecting an adjustment position of each part of the seat corresponding to the build of the occupant; a seat position adjusting means for the occupant to manually adjust a position of each part of the seat; and a seat position detecting means for detecting a position of each part of the seat. Build information selected with the adjustment position selecting means and positional information detected with the seat position detecting means are transmitted to an electronic control unit provided in the vehicle by wireless communication or wired communication. In the electronic control unit, proper positional information of each part of the seat estimated based on the build information and the positional information are checked against each other. When both pieces of information agree with each other, the occupant is notified of the agreement through a notifying means.
