A support base for a child safety seat includes a support leg operable to retract and expand at a bottom of the support base, a first and a second locking mechanism, and a linking assembly. The support leg includes multiple segments, and a first and a second sliding connection each of which respectively coupling two adjacent ones of the segments. The first locking mechanism includes a first latch operable to lock the first sliding connection, and a first actuating part operable to urge the first latch to move for unlocking the first sliding connection. The second locking mechanism includes a second latch operable to lock the second sliding connection, and a second actuating part operable to urge the second latch to move for unlocking the second sliding connection. The linking assembly couples the two locking mechanisms so that the first and second sliding connections can be concurrently unlocked.

A child safety seat assembly includes a shell body for defining a support base attachable to a child seat, a leg frame extendible downward from a bottom of the shell body, and a cushion part. The leg frame includes a first and a second tube segment attached with each other, the first tube segment being affixed with a fastener. The cushion part is affixed in the second tube segment adjacent to the fastener, and is formed as an integral hollow body including a first, a second and a third sidewall. The first sidewall faces the fastener, and the second and third sidewalls include inward recessed surfaces and are respectively connected with two side edges of the first sidewall. When the second tube segment is forced to displace relative to the first tube segment, the fastener and the first sidewall push against each other to cause deformation of the cushion part.

Disclosed herein is a system for securing a base of a child car seat in an associated vehicle using a safety belt of the associated vehicle. The system comprises a base configured to support a seat of the child car seat and a belt lock off mechanism. The belt lock off mechanism includes a first arm movable between (a) an unlocked position in which the first arm is not configured to tension the safety belt of the associated vehicle, and (b) a locked position in which the first arm is configured to tension the safety belt of the associated vehicle. A second arm of the belt lock off mechanism is configured to engage with and urge the first arm to move from the unlocked position to the locked position so as to tension the safety belt of the associated vehicle.

A child safety seat (1) for a vehicle, the child safety seat (1) comprises a seat body (2) and a frame (3) which is removably secured to or securable onto an existing vehicle seat (VS) in a rearward configuration, the seat body (2) comprising a back portion (20) and a seat portion (21), the frame (3) being pivotably attached to the back portion (20) of the seat body (2) such that, in use, the seat body (2) is arranged to pivot about the pivotable attachment to the frame (3) during a vehicular accident.

The disclosure provides an infant vehicle seat that is capable of independent movement. The infant vehicle seat may include a base including a shell enclosing a seating area and an infant restraint harness. The infant vehicle seat may include four legs, each pivotably mounted to the base and including a joint between an upper segment and a lower segment. The infant vehicle seat may include a first actuator for each leg coupled with the base and the respective upper segment and configured to pivot the leg with respect to the base. The infant vehicle seat may include a second actuator for each leg coupled with the upper segment and the lower segment and configured to bend and extend the leg. The infant vehicle seat may include a control system configured to translate an input command into a series of control signals for each of the first actuators and second actuators.

According to the application, a limiting device is used for limiting a pivoting of a side impact protection block in respect to a child safety seat, and the limiting device includes: a mounting portion, located on a seat body of the child safety seat and arranged close to the side impact protection block; and a restricting member, has a free end and is arranged on the mounting portion, such that the restricting member is movable between a locked position and a released position. In the locked position, the free end of the restricting member abuts against the side impact protection block to prevent the side impact protection block from moving in an unfolding direction in respect to the child safety seat, and in the released position, the free end of the restricting member is away from the side impact protection block to allow side impact protection block to move in the unfolding direction in respect to the child safety seat. The application also relates to a child safety seat including the limiting device according to the application.

A top rod adjusting mechanism includes is disposed between a base and a top rod of a child safety seat. The top rod adjusting mechanism includes a transverse frame, a threaded rod and a nut. The transverse frame is movably disposed on the base and installed on the top rod. The threaded rod rotatably passes through one of the transverse frame and the base in axial limitation. The nut is installed on the other of the transverse frame and the base and threadedly sleeved on the threaded rod. When the threaded rod and the nut rotate relative to each other to generate relative sliding movement, the traverse frame drives the top rod to move relative to the base. The top rod adjusting mechanism has advantages of simple structure and easy operation.

A support base for a child safety seat includes a shell, a belt clamp and a latching mechanism. The shell is adapted to receive a child seat thereon, and has a panel at an end thereof and a belt anchoring region adjacent to the panel, the belt anchoring region including a first and a second surface, the second surface being supported by the panel and connected with the first surface. The belt clamp is pivotally connected with the shell, and is operable to clamp a first and a second belt portion respectively adjacent to the first and second surface. The latching mechanism is operable to lock the belt clamp in a clamping state.

A headrest support structure applied to a safety seat is disclosed. The headrest support structure includes a buffer mechanism. The buffer mechanism is connected to a headrest and a seat of the safety seat. Elastic deformation of the buffer mechanism provides a buffer to the headrest and the seat. The headrest support mechanism provided by an embodiment of the present application has a high safety factor and provides a buffer to the headrest and the seat during an emergency brake for accident prevention. The present application further provides an infant carrier having the headrest support structure.

An infant car seat includes a seat base and a stability leg. The stability leg is rotatably disposed under the seat base. The stability leg includes an upper leg tube, a rotary member and a first latch. The upper leg tube includes at least one opening. The rotary member includes a pivoting portion and an encircling portion. The pivoting portion is rotatably connected to the seat base. The encircling portion is connected to the pivoting portion and slidably disposed on the upper leg tube. The first latch is disposed on the rotary member, and adapted to detachably engage with the at least one opening for constraining a movement between the rotary member and the upper leg tube.
