The backrest assembly including a first portion, a second portion slidably connected with the first portion, and a third portion slidably connected with the second portion. The lock includes a first latching part operable to lock and unlock the third portion with respect to the second portion, and a second latching part operable to lock and unlock the first portion with respect to the second portion, the second latching part being coupled to the first latching part so that the first and second latching parts are movable in unison relative to the backrest assembly.

An infant car seat is adapted for being installed on a seat carrier. The infant car seat includes a seat shell, a latch, a release unit, and a resilient member. The seat shell is formed with a receiving space having an opening. The latch is disposed in the receiving space, and is adapted for engaging with a ledge of the seat carrier. The release unit includes an actuating member operable to drive the latch to move from a rest position, where a portion of the latch protrudes out of the opening for engaging with the ledge of the seat carrier, to a retracted position, where the latch is retracted into the receiving space. The resilient member is connected between the seat shell and the latch for biasing the latch toward the rest position.

A construction machine includes a movable portion provided on an upper surface of a hood and pivotable along the upper surface of the hood, a fixer fixed to the upper surface of the hood to restrict a pivoting range of the movable portion, and a console supported by the movable portion. The construction machine further includes a guide to connect the movable portion to the fixer and guide the movable portion in a predetermined pivoting direction. The movable portion 6 has an opening whose dimension in the pivoting direction is larger than that of the fixer, and the fixer is located in the opening.

A side wing adjustment mechanism and an adjustable sitting device, the side wing adjustment mechanism includes: a pin arranged on the headrest; and an inclined grooves arranged on the side wing, a distance between a portion of the inclined grooves and the longitudinal center axis gradually decreases in a direction extending from bottom to top toward the headrest along a longitudinal center axis of the backrest, and the pin is slidable along the inclined grooves. According to the application, the side wing can be folded and opened at will, and the structure of the application is more inclusive. During the opening and folding process, puling of the headrest or pushing of the side wing can be performed more smoothly and labor-savingly, and the phenomenon of deflection and jamming can be avoided, such that the opening and folding process of the side wings is smoother.

A quick acting belt tensioning mechanism for securing a child safety seat into a vehicle having a tensioning member with a hook-like engagement structure rotatably mounted on the safety seat adjacent to a belt path for a vehicle seat belt. Engaging the seat belt in the engagement structure and rotating the tensioning member by movement of the lever tensions the seat belt by wrapping the seat belt around the tensioning member. The lever is slideably disposed on the tensioning member to close the opening of the hook-like structure and prevent disengagement of the seat belt therefrom and to inhibit rotation of the tensioning member to the tensioned position unless the lever is properly positioned. A latching mechanism is provided to restrain the tensioning member and lever in the tensioned and closed position. The seat shell and lever may include structures to further constrain seat belt tensioning unless the lever is properly positioned.
