Abstract

The invention relates to a child restraint for use in a forward facing direction in automobiles, especially for location in the middle of the rear seat of the automobile. The restraint comprises a frame (1) which can be secured on the rear seat (2). The frame (1) also includes anchoring points for a normal three point safety belt (5).

Description

Child restraint
This invention relates to a forward facing child restraint for use in automobiles. Such restraints are well known and have been used since many years.
The more modern type of chi ld restraints uti lizes the ordinary three point safety belt to restrain both the restraint itself and the child therein. These known restraints require a full adult three point webbing, and can thus only be used in the front and rear outboard seats, where three point webbings are mounted.
The object of this invention is to create a device which allows the use of a full three point belt, and thereby the use of a child restraint in the middle of the automobile rear seat. Such a restraint is highly desirable for families with more than two children.
This invention relates to the manner in which such a device can be realized and adapted for use in the middle rear seat position. This seating position is almost universally equipped with a two point lap safety belt. Three-point safety belt is, however, not standard equipment in any modern automobile in the middle rear seating position.
The anatomy of a child differs from that of the adult in many ways. Two aspects, in particular, make the use of the adult safety belts difficult, and in certain respects unsafe, for children. Children lack the bone outcroping of the hip which in adults prevents the lap portion of the safety belt from penetrating the abdomen. In other words, the inner organs of the child are in jeopardy when the child uses unmodified adult lap belts. Secondly, the geometry of the shoulder belt is poorly adapted to the child, so that the diagonal portion of the webbing crosses the neck and clavicle, rather than the stronger sternum.
A poor fit between the child and the webbing leads to a phenomenon called "submarining", in which the child's body moves about during the course of an accident, slips under the webbing and estends forward. In actual accidents aubmarining can lead to extensive injuries, including fracture of the spinal cord caused by the heavy loading passed onto the neck. It is therefore important to devise a booster system which adequately can utilize the adult webbing. In particular, correctly positioned three point safety belts are highly superior in terms of restraint capacity. It is therefore highly desirable to employ three point safety belts for all child passengers.
As mentioned above the modern automobile does not offer three point safety belt in the middle position. The basic difficulty is that most automobiles lack structurally sound members in the position required for the third, superior, anchor point. In particular estate cars lack structures appropriate for the superior anchor point.
The invention proposes to locate a self-supporting structure, preferably formed by metal tubing, which provides a framework that locates, supports and fixes the three point safety belt and surrounds the child booster or booster seat. The following objects should be attained by such a device: a) the device must absorb and redirect the high loading that the webbing exerts in a collision, b) the device must be adaptable for most current automobiles, c) the device must not overly intrude on the passenger space available to other rear seat users.
The objects of the invention are obtained by a device in accordance with the claims.
The invention will now be described in form of a non limiting embodiment, shown on the appended drawings. In Fig. 1 is shown an overall view of the device according to the invention, shown located on the rear seat of an automobile, in Fig. 2 is shown the device together with an appropriate booster seat, in Fig. 3 the device in use by a child passenger strapped in the device, in Fig. 4 is schematically shown the fastening and supporting of the device on the rear seat middle position of an automobile, and in Fig. 5 is shown a frame portion for the device in accordance with the invention.
The device as shown in Fig. 1 incorporates a frame 1 resting on the rear seat 2 of an automobile. To the lower part of the frame 1 is connected a leg portion 3, which is extensible as will be described hereinafter, and which leg portion 3 is supported on the floor board 4 of the automobile. The frame 1 also contains an upper anchoring point as well as two lower anchoring points for a three point safety belt 5. The safety belt can preferably be a roller belt. As shown in Fig. 1 the upper part of the frame 1 is covered by an upholstery 6 including a head rest at the uppermost part.
As shown in Fig.2 the lower part of the frame 1 is adapted for reception of a booster seat 7, which preferably is detachable to facilitate the anchoring of the frame 1 to the automobile chassis. The booster seat 7 is resting on the upper surface of the automobile rear seat 2.
Fig. 3 shows a child passenger placed on the booster seat 7 and strapped by means of the three point safety belt 5 anchored to the frame 1.
In Fig. 4 is schematically shown how the frame 1 can be anchored to the automobile chassis by means of an anchoring means 8. The anchoring means 8 can e.g. be any sort of webbing which is strong enough to take up the maximum loads that can be applied thereon and is preferably secured to the automobile chassis under the rear seat. As anchoring means can also eventually be used the ordinary automobile two point lap safety belt, and the frame is preferably formed so that the lap safety belt can be slipped through slots in the frame near its supporting points against the rear seat. For a better carrying of the loads in a collision a leg portion 3 is connected to the frame 1, as mentioned above. The leg portion is extensible in respect to the frame so that it irrespectively of the inner dimensions of the automobile with its bottom part can be supported on the floor board 4 of the automobile. Preferably the leg portion 3 is of a tubing of somewhat smaller or greater dimension than the tubing of the frame so that the leg portion can be slided on the inside or outside of the frame, and the leg portion can preferably be secured to the frame in a choosen position by means of tightening bolts 9. The leg portion 3 is provided with an arch 10 to be placed over the transmission tunnel 11 of the automobile.
By forming the frame with a substantially triangulated base, as shown in Fig. 5, the device can be manufactured with relatively slim tubing and will not require more space than an adult passenger, and thus not intrude on the rear outer seating positions.
