Benefits of technology

[0010]The aim of the present invention is to provide a tension regulator for a safety belt of a seat, in particular a child safety seat, that will enable a simple and inexpensive solution of the drawbacks set forth above.

Problems solved by technology

The known solutions of the type just described are far from satisfactory, in so far as the nipping action exerted by the movable transverse edge is not sufficient to withhold the belt when the tension of the belt is relatively low or else when the two portions of strap are not parallel for reasons of installation.
In addition, the solution illustrated in EP0040062 envisages an additional cross member, which projects laterally from the covering in order to be able to displace the movable transverse edge against the action of the spring and slacken the grip exerted by the nipping action, so that it has a relatively high number of components and requires long times and high costs for production and assembly.
In addition, the plastic material used for structural parts, guide parts, and / or retention parts in the regulators of a known type is often subject to failure.

Embodiment Construction

[0021]In FIG. 1, the reference number 1 designates as a whole a child safety seat for carrying a child in a motor vehicle. The child safety seat 1 comprises a sitting surface 5 and a backrest 6, and is set on a seat 7 of the motor vehicle, for example, a rear seat. The child safety seat 1 is fixed to the seat 7 via a coupling assembly 8 (known and not described in detail), of the type commonly referred to as “isofix”, and via a safety belt 9, which withholds the top end of the backrest 6 against the backrest of the seat 7, preventing the safety seat 1 from tilting forwards.

[0022]The belt 9 is of a static type, i.e., is without automatic roll-up devices (winders) and pretensioner safety devices, and comprises a strap 10 provided, at the bottom end, with a spring catch 11, which is fixed in a way illustrated schematically, for example is anchored by snap action, to a half-ring 12 fixed on a portion of the vehicle body or of the structure of the seat 7.

[0023]The strap 10 comprises an i...

Abstract

A tension regulator for a safety belt of a seat, in particular a child safety seat, is provided with a metal body having a contrast cross member and with a slider, which is also made of metal; the slider has a retention cross member, wound on which is a strap of the safety belt, and is slidable with respect to the body for exerting a nipping action on said strap between the retention cross member and the contrast cross member; the body has a guide cross member, which defines, with the contrast cross member, a passage that can be engaged by the strap for keeping the strap folded on an edge of said contrast cross member.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from European Patent Application No. 07425510.0, filed on Aug. 3, 2007.BACKGROUND OF THE INVENTION[0002]1) Field of the Invention[0003]The present invention relates to a tension regulator for a safety belt of a seat, in particular to a regulator for a safety belt of a static type of a child safety seat.[0004]2) Discussion of Related Art[0005]Belts are known comprising a first strap and a second strap connected to one another by a tension regulator defined by a buckle. The first strap is fixed to the regulator, whilst the second strap passes in a series of openings made in the regulator and has a free end that can be pulled manually so as to slide along the regulator and set the belt in tension.[0006]For example, the patent No. EP0040062 illustrates a regulator, which is fixed, at one end thereof, to the first strap and comprises a plate and a covering, which is made of plastic material and comprises a tran...
