The invention relates to a structural element (10) for a child car seat (100), which comprises: —a first portion (11), for constituting a back part of a child car seat for a first child car seat group, or for constituting a seat part of a child car seat for a second car seat group; and —a second portion (12), for constituting a back part of the child car seat for the second child car seat group, or for constituting a seat part of the child car seat for the first child car seat group; —the first portion (11) and the second portion (12) comprising a gas tight envelope enclosing a plurality of layers, the gas tight envelope being in a first flexible state under atmospheric pressure, and in a second rigid state when a negative pressure is applied; and —the first portion (11) and the second portion (12) comprising through holes (110; 120, 121) configured for straps of a belt harness (60). The invention also relates to a multi-group child car seat (100), comprising a frame (500), couplable to a seat of a vehicle and a child car seat structure (10).

A child safety seat includes a seat shell, a headrest and a side protection part. The seat shell has a seat portion, a backrest portion and a sidewall, the sidewall protruding forward from the backrest portion. The headrest is connected with the backrest portion and is movable along the backrest portion, the headrest having a side support portion protruding forward. The side protection part is disposed adjacent to the sidewall at an inner side thereof, the side protection part extending along the inner side of the sidewall from a location adjacent to the seat portion toward a top of the backrest portion, a portion of the side protection part being located between the sidewall and the side support portion of the headrest.

A seat (1000) may include mounting components (1054a. 1054b) that may mate with corresponding components on other assemblies. The seat may include one or more features that may rotate or move to provide for coupling to the one or more assemblies.

The present disclosure discloses a child safety seat and a side impact protection mechanism thereof, the side impact protection mechanism is provided at a backrest of the child safety seat and includes a side impact protection block and a self-locking structure. The side impact protection block is movably fitted to the backrest and has a folding position in which the side impact protection block is inwardly folded in the backrest and an unfolding position in which the side impact protection block is outwardly unfolded from the backrest. The self-locking structure automatically moves to a position that blocks the side impact protection block in the unfolding position from switching to the folding position when the side impact protection block is switched from the folding position to the unfolding position, the self-locking structure is fitted to the side impact protection block or the backrest, and the backrest and the side impact protection block shields the self-locking structure to block a release operation of the self-locking structure by an operator, so that the side impact protection block cannot be inwardly folded into the backrest after the first use, thereby effectively preventing the side impact protection block from being accidentally folded during the side impact to provide a side impact protection effect.
