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.

A stroller having a folding frame which serves as basis for a stroller which can be used in a seat configuration for the transportation of a child, and which can be alternatively used in a cart configuration wherein the seat-bottom and seat-back are hingedly interconnected and configured to fold out into a cart for transporting goods such as groceries.

A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

A child carrier includes: a seat portion; a buckle movably provided on the seat portion; a backrest portion connected to the seat portion and extending upward, the backrest portion having a plurality of adjustment holes formed therein from bottom to top; and a shoulder strap having a fixed end and a free end, the fixed end being fixed on a rear side of the backrest portion, the free end passing through one of the plurality of adjustment holes and being removably connected to the seat portion.

According to the application, a handrail mechanism for a baby carriage includes: a shell having an accommodating space; a handrail connecting part having a free end and a pivotal end, the pivotal end being pivotally connected to the shell; and an elastic member arranged in the accommodating space of the shell, the elastic member having one end connected to the shell, and the other end connected to the handrail connecting part. Among them, the handrail connecting part is able to be pivoted between a bounced up position and a pressed down position, the free end of the handrail connecting part is away from the shell in the bounced up position and is close the shell in the pressed down position, the elastic member is arranged to bias the handrail connecting part toward the bounced up position, and when an external force is applied to overcome an action of the elastic member, the handrail connecting part is able to be pivoted from the bounced up position to the pressed down position. A baby carriage including the handrail mechanism is also disclosed.

A collapsible seat assembly is mounted on a frame of a stroller, and includes a joint member, a backrest support member, a leg support member and a locking mechanism. Each of a pivot portion of the backrest support member and a pivot portion of the leg support member is pivotably mounted on the joint member. The locking mechanism is disposed between the pivot portions to lock or unlock the backrest and leg support members. The locking mechanism is configured to be actuated to move from a locking position to an unlocking position by the operation of the frame of the stroller from an unfolded state to a folded state. A stroller having the collapsible seat assembly is also disclosed.

The present disclosure relates to a seat cover assembly of a baby stroller including a seat cover, a support structure and a pivot portion. The support structure is disposed in the seat cover and includes a first plate member and a second plate member that are movably connected. A seam is formed between the first plate member and the second plate member, and a width of the seam is less than a sum of a thickness of the first plate member and a thickness of the second plate member. The pivot portion is opposite the seam and close to a surface of the first plate member and a surface of the second plate member.

A frame structure of a perambulator, a child seat, an infant carrier or the like, includes a profiled frame element which along a profile direction of the frame element has a substantially constant cross-section, wherein the profiled frame element includes an at least predominantly closed cross-section, and wherein the profiled fame element has an inwardly projecting first protrusion which is configured to be brought into engagement with a fastening arrangement.
