DESCRIPTION:
BRIEF SUMMARY
The invention relates to a child's seat comprising a seat portion and a back portion, which child's seat can be secured in a vehicle by means of a three-point seat belt present in said vehicle, which three-point seat belt is connected to the vehicle with a first end and with a second end and which can be detachably secured to a belt buckle provided in said vehicle by means of a belt tongue provided between said ends, whereby in the mounted position of the child's seat in the vehicle the first end of the belt is positioned near an upper side of said back portion, the second end is positioned under the first end, near the seat portion, and the belt tongue connected to the belt buckle is positioned on a side of said seat portion remote from said second end, whereby the child's seat near the upper side of the back portion is provided with at least one clamping device comprising a housing and a tightening device positioned within said housing, by means of which a belt portion extending between said belt tongue and said first end can be pulled in a tightening direction away from said back portion and be locked against movement with respect to the clamping device in a locking direction opposed to said tightening direction, said tightening device is provided with a locking pin extending in the transverse direction of the belt, which locking pin can be coupled to the belt, whereby said locking pin is capable of movement in and opposed to the tightening direction, and in a direction away from the belt, transversally thereto.
With a similar child's seat known from British Patent Application GB-A-2,288,202 the child's seat is secured in the car by means of a three-point seat belt present in the car. The belt is thereby connected to a belt buckle present in the car by means of a belt tongue. The three-point belt is connected to the car with both ends and consequently must be introduced into the clamping device in a direction transversely to the longitudinal direction of the belt. The shoulder belt is thereby guided into the clamping device secured to the child's seat, for example, and subsequently tightened in a desired tightening direction.
The belt must be locked against movement in the clamping device in a second locking direction opposed to said first direction, in order to prevent undesirable movement of the child's seat with respect to the belt. The child's seat can be taken out of the car by removing the belt from the buckle and from the clamp.
The clamping device known from British Patent Application GB-A-2,288,202, is provided with a C-shaped part comprising a baseplate and two flanges extending towards each other. A tightening device is located between said baseplate and said flanges. The belt is introduced into the C-shaped part through the flanges, so that the belt will be positioned between the tightening device and the flanges. The belt is capable of movement in a first tightening direction whilst being locked against movement in a second locking direction. When the clamping device is used for securing a child's seat in a car, forces will also be exerted on the belt and on the clamping device in directions transversely to the belt in the event of an accident or a collision.
One drawback of the known device is the fact that when such forces occur, the C-shaped part can bend open relatively easily, as a result of which the belt will move out of the C-shaped part and the child's seat will no longer be connected to the car. This is undesirable, cf course. Another drawback is the fact that the C-shaped part is relatively weak, as a result of which the tightening force exerted on the belt will vary.
Another drawback of the known device is the fact that the locking pin is mounted in a frame which is secured in the housing. Due to the additional frame the clamping device is relatively thick and relatively complicated to manufacture.
The object of the invention is to provide a child's seat when the drawbacks are avoided.
This object is accomplished in the child's seat according to the invention in that the housing
