Abstract: A safety seat for automobile passengers and for children which is formed from permanently deformable structural stock having a body contoured semi-flexible seat clipped to and in support of a portion of the structural frame. In turn, the frame supports the seat. The seat and frame combination is usable in both directions and the safety seat includes a deformable crash pad which in one direction is in interference relation to the head and shoulders of a child in said seat positioned for automotive use. The child''s seat as described is supported on a bench type or lock back automobile seat and is secured in place by an ordinary seat belt. The back of the automotive seat forms a back support for the child. The crash pad is forward of and obstructs the creash path of the head and shoulders of the child. As the child or passenger impacts against the crash pad, the light weight structural frame deforms to absorb and spend the energy in avoidance of ''''spring back.'''' Hence, the device employs what could be characterized as an inertial lever accomplishing a calculated collapse on collision impact situations. When removed from the automobile, the infant is reversed in direction and the chair acts as a chair extension or high chair in restaurants and the like, the barrier then serving as a head and back rest.

Abstract translation: 用于汽车乘客和儿童的安全座椅，其由具有身体轮廓的半柔性座椅的永久变形的结构性坯料形成，所述身体轮廓半柔性座椅被限定在并支撑结构框架的一部分。 反过来，框架支撑座椅。 座椅和框架组合可在两个方向上使用，并且安全座椅包括可变形的碰撞垫，其在一个方向上与位于用于汽车使用的所述座椅中的儿童的头部和肩部具有干涉关系。 如上所述的儿童座椅支撑在台式或汽车座椅上，并通过普通安全带固定在适当位置。 汽车座椅的后面形成了对孩子的后背支撑。 防撞垫前面并阻挡了小孩的头部和肩膀的皱纹路径。 当小孩或乘客撞击碰撞垫时，重量轻的结构框架变形以吸收和消耗能量以避免“弹回”。 因此，该装置采用可以表征为惯性杆的碰撞冲击情况下的计算崩溃的特征。 当从汽车中取出时，婴儿的方向颠倒，椅子作为餐厅等的椅子延伸部或高脚椅，屏障然后用作头部和靠背。
