Abstract: A safety seat for a vehicle that comprises a static part attachable to an anchor of a vehicle, at least two energy absorption elements mounted on the static part, each designed to absorb a different amount of energy and a dynamic part adapted to accommodate a child and comprising at least one connector which is engaging at least one of the at least two energy absorption elements, the at least one engaged energy absorption element is adapted to a weight range of a child, so as to absorb impact energy applied on the dynamic part via the static part, thus extending along a longitudinal movement between the static part and the dynamic part.

Abstract: A safety seat for a vehicle includes a rigid frame concavely shaped to accommodate a person, and a headrest shaped to accommodate a head of the person. The headrest has two headrest side panels flexibly connected to the rigid frame. A horizontally disposed lever is positioned at the back of the rigid frame which is pushed by an external side impact. A vertically disposed lever adjacent to the horizontally disposed lever is pushed vertically by movement of the horizontally disposed lever, and moves the two headrest side panels to a closed position on the sides of the head.

Abstract: A system for guiding installation of car seat base and a corresponding car seat includes sensors mounted on the car seat base for detecting a progress in a plurality of sequential installation steps. The installation steps are required for installing the car seat base and the corresponding car seat on a vehicle seat. The car seat base further includes light emitting elements arranged at various locations on the car seat base, each location corresponding to one of the installation steps. A processor is adapted to execute code instructions for, in response to outputs of the sensors, identifying completion of a current installation step. The processor is further adapted to instruct a suitable light emitting element to indicate a location corresponding to an installation step following the current installation step. An anti-rebound device includes a spring or piston that adaptively adjusts in response to an impact and a locking mechanism.
