Abstract: A transportation device includes a frame and a carrier. The frame includes a rail, a fixing base, an unlock member and a sliding member. The rail has a first engaging hole with a first retaining wall. The unlock member has an engaging portion. An end of the sliding member abuts against the unlock member. The carrier includes a connecting base with a rib. The connecting base is connected to the fixing base to install the carrier on the frame. When the carrier faces a first direction, the rib pushes the sliding member to push the unlock member, such that a length of the engaging portion protruding from the fixing base is reduced. When the carrier faces a second direction, the rib is staggered with the sliding member.

Abstract: A child seat includes a front guard and a backrest frame respectively connected pivotally with the seat portion about a first and a second pivot axis, and a folding mechanism including a latch pivotally connected with the seat portion about a third pivot axis for locking and unlocking the front guard with respect to the seat portion, and a linking part coupled to the latch and pivotally connected with the backrest frame about a fourth pivot axis. A rotation of the backrest frame from a deployed position toward a collapsed position causes a displacement of the linking part that urges the latch to unlock the front guard. The first, third, second and fourth pivot axes are arranged in that order along a direction from a front to a rear of the seat portion when the backrest frame is in the collapsed position and the front guard in a folded position.

Abstract: The present invention discloses a backrest angle adjusting mechanism including a first support, a second support, a locking member and a reset member. The first and second supports are pivotally connected to each other and are respectively connected to a backrest tube and a stroller frame, and multiple engaging stages are formed between the first and second supports. The locking member is slidably provided between the first and second support, and has a lock position and a release position. The locking member is engaged at any engaging stage when at the lock position; when the driving member moves, the locking member is driven to slide and depart from the engaging stage and becomes located at the release position, thereby implementing angle adjustment of the backrest tube. During a folding process of the stroller frame, automatic folding of the backrest tube can be achieved by folding the frame stroller or by a seat fabric pulling the backrest tube that then moves with the stroller frame, thereby better simplifying operations of angle adjustment of the backrest tube and folding of a baby stroller. The present invention further discloses a baby stroller having the backrest angle adjusting mechanism.

Abstract: A seat includes a support base, an unlock member and a lock member. The support base has at least one through hole. The unlock member is movably disposed on the support base and has at least one first driving portion. The lock member is movably disposed on the unlock member. The lock member has at least one lock portion protruding from a surface of the support base through the at least one through hole and at least one second driving portion abutting against the at least one first driving portion. When the unlock member is forced in a first direction to move, the at least one lock portion is forced to move along the at least one first driving portion through the at least one second driving portion and retracts into the support base in a second direction different from the first direction.
