DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a method of installing a rear-facing child car seat on a passenger seat in a car, which child seat comprises a seating part and a supporting arm projecting from the seating part, which supporting arm is foldable away from and towards the seating part, the child seat being placed in a working position with the seating part on the seat part of the passenger seat and with the supporting arm folded against the backrest part of the passenger seat and being anchored in this position. The invention also relates to an arrangement for such an installation.
PRIOR ART
Installation methods of the kind mentioned above have been used for many years in connection with a non-folding as well as a folding supporting arm, the required anchoring normally being achieved with the aid of the seat belts of the car or similar special straps.
Although such anchoring generally has turned out to function well, the use of the seat belt of the car means that the installation becomes somewhat complicated and that the anchoring may be unsatisfactory if the tightening of the seat belt is not done with great care.
It has also been suggested that the anchoring of child car seats should be standardised by employing special fastening means arranged in the car, such as two fastening members at the front edge of the child seat and two fastening members at the back edge of the child seat. However, it has not yet been possible to establish such a standard.
OBJECT OF THE INVENTION
The object of the present invention is to provide a method of and an arrangement for installing child car seats, whereby the need for employing the seat belt of the car for the anchoring is eliminated, whereby the anchoring is very simple, secure, flexible and inexpensive, whereby the required fastening means in the car are simple and easy to install and furthermore can be designed in a way that does not require a fixed arrangement in the car, and whereby no impediments are created which might make it difficult for car manufacturers to introduce their own new specific design solutions.
SUMMARY OF THE INVENTION
The above-mentioned object is achieved by a method and an arrangement which exhibit the features stated in the appended claims.
The basis of the invention is thus an understanding of the fact that the anchoring of a child car seat, placed in a working position, which is being held in place by a combination of supporting arm engagement with the backrest part of the passenger seat and child seat engagement with special fastening means in connection with the transition between the backrest part and the seat part of the passenger seat, can advantageously be achieved by employing the folding movement of the supporting arm for making contact with the backrest part. In other words, when the child seat has been placed on the seat part of the passenger seat and initial engagement with said fastening means has been achieved, the anchoring engagements are tightened by the supporting arm being folded from a folded-back position closer to the seating part of the child seat to a lowered position with the supporting arm, preferably at least its free end part, in pressing engagement with the backrest part of the passenger seat. To the skilled person it will easily be apparent that the required support for the seating part of the child seat can suitably be obtained from the seat part of the passenger seat and/or the dashboard of the car and/or a special support against the floor of the car, the latter suitably by means of a leg fixed to the back of the child seat, which leg can be locked in the required extended position.
According to the invention, it has been found to be particularly advantageous to use a two-step anchoring system. Thus, in the first step, basic anchoring is achieved by the supporting arm being pushed by hand to an initial engagement with the backrest part of the passenger seat. In the second step, final anchoring is achieved by means of a special after-tightening operation, which preferably is effected b
