Abstract
Abstract A child restraining device adapted to be secured on a vehicle seat and having a pair of legs adapted to engage the floor structure of the vehicle. The legs, in combination with a conventional seat belt, are designed to retain the device in a stable position on the vehicle seat with the child disposed in an inclined supine position facing either forwardly or rearwardly. The device includes a shield located in front of the child. The arrangement is designed to reduce the probability of serious head or other injury to a child in the event of a collision.

Claim 1
Independent Claim
378 words
In a vehicle of the type having a seat defined by a seat cushion and a backrest and also having a rigid floor structure, a child restraint device to protect the child in the event of an impact comprising a walled enclosure in which the child is adapted to be positioned in a supine position, said enclosure including a shape retaining shell, means on said enclosure for preventing the child therein from being thrown therefrom in the event of vehicle impact, said shell being disposed with a lower portion thereof supported on the seat cushion so that the spine of the child therein extends generally longitudinally of the vehicle and is inclined to the horizontal, a pair of support legs connected at their upper ends to the enclosure adjacent each side thereof and having a support position wherein they extend downwardly from the enclosure to engage the floor structure of the vehicle at their lower ends forwardly of the vehicle seat, restraining belt means anchored to the floor structure of the vehicle adjacent the rear of the vehicle seat and extending therefrom in an upward and forward direction and connected at its upper end with said enclosure rearwardly of the connection between said support legs and enclosure and means for preventing said legs from swinging in a direction forwardly and upwardly relative to the enclosure substantially beyond said support position, said restraining belt means when tightened cooperating with said legs to urge said enclosure downwardly against said seat cushion, said support legs and said belt restraining means being arranged relative to each other so that the plane extending through the connection points of the belt means with the vehicle floor structure and the enclosure and the plane extending through the lower ends of said legs and the connection between the legs and the enclosure are inclined towards each other and intersect at an axis which is disposed horizontally above the center of gravity of the enclosure with the child positioned therein whereby any tendency for the enclosure to tilt sidewise or for the upper end thereof to tilt downwardly and forwardly about the connection of the belt means and enclosure as a result of a collision is resisted by the joint effect of said legs and belt means.
