Abstract: A mechanism disposed between a frame structure and a base structure, the mechanism comprising a damper including a piston rod. The damper is mechanically connected between the frame structure and the base structure in a normal mode of operation. The damper enables a longitudinal and suspended upward and downward movement of the frame perpendicular to a plane. An energy-absorbing arrangement that includes a plastically deformable absorbing element. The plastically deformable absorbing element is adapted to plastically deform in response to stresses greater than a predetermined threshold stress along an axis perpendicular to the plane. A bar mechanically attached to the plastically deformable absorbing element and having an engagement portion.

Abstract: A shell for an infant seat comprises a carbon fiber structure reinforced by one or more reinforcing members of a material other than carbon fiber forming a shell shaped to accommodate an infant. The one or more reinforcing members is located on the concave side of the structure, e.g. between the structure and the infant. The structure and the one or more reinforcing members are fixed to each other so as to prevent relative movement between them in use. The reinforcing members may be made from plastic and may be overmolded or glued on the carbon fiber structure.

Abstract: A portable baby seat (10) has a longitudinally oriented carrying handle (100) that is coupled to the baby seat shell (300) in parallel with the baby seat longitudinal axis x, coupled to the back of the seat as well as the bottom of the structure thus assisting in reducing loads exerted on the portable baby seat.

Abstract: Impact absorption devices and methods for a vehicle's seat are provided. Devices comprise vertical support(s), energy absorbing element(s) hingedly connected to the seat and hingedly connected to the vertical support; and at least four rods hingedly connected to the seat and hingedly connected to the vertical support. The rods are positioned to geometrically guide a relative motion of the seat with respect to the vertical support upon impact, and to direct the impact energy absorption by the energy absorbing element(s). The rods may be configured according to prevailing spatial relations and required energy absorption with respect to expected intensities and directions of impacts. The devices may be configured with any energy absorption element(s), may be augmented by vibration damping or implemented using electromagnetic dampers.

Abstract: The present invention discloses a method and apparatus for minimizing accelerations during impacts such as those encountered in motor vehicle accidents, helicopter and airplane crashes, explosions, and the like. The preferred embodiment takes the form of a helical spring-like member (100), designed to experience plastic deformation over a desired deformation length, under a given impact load threshold. The spring-like member is preferably installed in a mechanical linkage that is flattened under impact, straining the spring-like member in a predictable fashion. The operating characteristics of this system [namely the stress-strain curve, and thus the deformation length, impact load threshold, and acceptable load range for the system to be protected] can be easily controlled by varying the device dimensions and installation configuration.
