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
- This application claims priority from European Patent Application No. 07425510.0, filed on Aug. 3, 2007.
- 1) Field of the Invention
- 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.
- 2) Discussion of Related Art
- 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.
- 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 transverse edge, which is movable under the thrust of a spring in order to nip the second strap of the belt against a contrast cross member of the plate and keep the belt stationary after the tensile force has been increased by pulling the end of the second strap.
- 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 fact, in these conditions, the second strap of the belt remains in a position substantially aligned with the slit defined by the transverse movable edge and the contrast cross member, without forming substantially any angle or fold around the contrast cross member, so that the second strap is able to slide in said slit in spite of the fact that it is subjected to the nipping action.
- 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.
- 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.
- Provided according to the present invention is a tension regulator for a safety belt of a seat, in particular a child safety seat, the regulator comprising:
-
- a body made of a single piece of metal material and comprising:
a) an attachment portion, and
b) a contrast cross member; - a retention cross member, coupled to said body in a position such as to remain wound, in use, by a second strap of said safety belt, and movable in a longitudinal direction between:
a) an advanced position towards said contrast cross member, for exerting a nipping action on said second strap between said contrast and retention cross members, and
b) a retracted position, for leaving said second strap free to slide in the space between said contrast and retention cross members; and - an actuation portion, which can be pressed manually for displacing said retention cross member into its retracted position;
said regulator being characterized in that said body comprises a guide cross member defining, with said contrast cross member, a passage that can be engaged by said second strap for maintaining a fold of said second strap around an edge of said contrast cross member.
- a body made of a single piece of metal material and comprising:
- For a better understanding of the present invention a preferred embodiment is now described, purely by way of non-limiting example, with reference to the attached drawings, wherein:
-
FIG. 1 is a side view of a preferred embodiment of the tension regulator for a safety belt of a seat, in particular a child safety seat, according to the present invention; -
FIG. 2 is an exploded perspective view at an enlarged scale of the tension regulator ofFIG. 1 ; -
FIG. 3 is a cross-sectional view according to the line III-III ofFIG. 2 ; -
FIG. 4 is similar toFIG. 3 and shows the tension regulator with its own components assembled in a configuration of use; and -
FIG. 5 is a perspective view of a different safety belt applied to which is the tension regulator of the present invention. - In
FIG. 1 , thereference number 1 designates as a whole a child safety seat for carrying a child in a motor vehicle. Thechild safety seat 1 comprises a sittingsurface 5 and abackrest 6, and is set on aseat 7 of the motor vehicle, for example, a rear seat. Thechild safety seat 1 is fixed to theseat 7 via a coupling assembly 8 (known and not described in detail), of the type commonly referred to as “isofix”, and via asafety belt 9, which withholds the top end of thebackrest 6 against the backrest of theseat 7, preventing thesafety seat 1 from tilting forwards. - The
belt 9 is of a static type, i.e., is without automatic roll-up devices (winders) and pretensioner safety devices, and comprises astrap 10 provided, at the bottom end, with aspring 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 theseat 7. - The
strap 10 comprises anintermediate portion 14, which carries atension indicator 31 and is connected to the end of astrap 17 via atension regulator 19 defined by a buckle. The top end of thestrap 10 is defined by aportion 18, slidably inserted and withheld in theregulator 19, as will be described more fully in what follows. - The ends of the
strap 17, instead, are defined by twoloops 22, 23: theloop 22 is wound in a fixed position around a cross member 21 (FIG. 2 ) of theregulator 19, whilst theloop 23 is wound in a fixed position around an engagement element, defined for example by apin 24, fixed to atop portion 26 of thebackrest 6. - With reference to
FIGS. 2 to 4 , theregulator 19 comprises abody 32 and aslider 33, slidably coupled to one another in a rectilinearlongitudinal direction 34, which is aligned with thestrap 17 when thebelt 9 is tensioned. - The
body 32 is made of a single piece of steel and comprises aplane plate 35 having a rectangular throughopening 36, which is defined by thecross member 21, by across member 37 for retention of theportion 18 and by twolateral portions 38 parallel to thedirection 34. - The
body 32 further comprises twolateral appendages 39, which extend from the edges of theportions 38 and are bent back inwards in a position facing atop surface 41 of theplate 35 so as to form, together with theportions 38, respective C-shaped portions and, hence,respective guide channels 42. - The
channels 42 are closed, in a position adjacent to thecross member 21, byrespective walls 43, which are orthogonal to thedirection 34 and form part of theappendages 39. Thechannels 42 house, at their ends, respectiveelastic elements 45, defined in particular by helical springs, which are arranged so that they rest, on one side, against thewalls 43 and, on the other side, againstrespective side projections 47 of theslider 33 so as to push theslider 33 in thedirection 34 away from thewalls 43 and thecross member 21. - The
body 32 moreover has a throughopening 48 separated from theopening 36 by thecross member 37 and defined not only by thecross member 37, but also by across member 49 for guiding theportion 18, and by two lateral radiusingportions 50, which define the prolongation of theportions 38 and are inclined with respect to theportions 38 in a direction opposite to theappendages 39 and to theslider 33. - The
cross member 49 lies in a plane parallel to thecross members cross members - Once again with reference to the attached figures, the
slider 33 is defined by a steel plate, which is obtained starting from a sheet of metal plate, which is blanked to obtain the external perimetral rim and an intermediate throughopening 52 and is then bent to obtain the lateral profile shown inFIG. 4 . - The
opening 52 is defined by: arear cross member 53, having a bottom face which slides in contact with thesurface 41; atransverse portion 54, facing thecross member 53 and having afront end appendage 55, which is external to thechannels 42 and is bent in a direction opposite to thecross member 49 so as to form a pushbutton; and twolateral portions 56, which are substantially aligned with theprojections 47. In particular, the distance between the bottom face of thecross member 53 and the top face of theprojections 47 and of theportion 54 approximates by defect the height of thechannels 42 to guarantee guide coupling (FIG. 4 ). - According to what is shown in
FIG. 4 , theportion 14 enters theregulator 19 passing on top of thecross member 49. The part that effectively engages theregulator 19, defined by theportion 18, passes in the opening 48, underneath thecross member 37, and then folds in order to pass through theopening 36. Theportion 18 is then wound around thecross member 53 of theslider 33, and then comes back into the opening 52. When it leaves the opening 52, theportion 18 enters theopening 36 again and is folded around a bottom andrear edge 60 of thecross member 37. - Next, the
portion 18 passes underneath thecross member 37, and then again in theopening 48 above theportion 14, where it can be pulled manually by a user for tensioning thebelt 9. - The
slider 34 can move under the guide of thechannels 42 between an advanced position, in which it is pushed by thesprings 45 for exerting a nipping action on theportion 18 between thecross members portion 18 in a fixed position, and a retracted position, in which it leaves theportion 18 the space necessary for sliding between thecross members openings - In particular, in order to release or distend the
belt 9, for example in order to slide theloop 23 out of thepin 24, theslider 33 is translated into the retracted position by manually pressing theportion 54. - The opening 48 guides the
portion 18 so as to keep it folded on theedge 60, which prevents thestrap 18 from setting itself orthogonal to theplate 35 when thebelt 9 is not tensioned and, hence, possibly sliding out of theregulator 19 even though it is gripped by the nipping action between thecross members -
FIG. 5 shows thesame regulator 19 applied to another safety belt of a static type, designated by thereference number 62. InFIG. 5 , wherever possible, the same reference numbers have been used as the ones already used for the corresponding components shown inFIG. 1 . - The
belt 62 is carried by the structure of thechild safety seat 1. The ends of thebelt 62 extend on the outside of thechild safety seat 1 and are fixed to respective engagement devices 64, which form part of theassembly 8 and are provided for being engaged to respective pins (not illustrated) fixed to the body or structure of theseat 7, in order to withhold thechild safety seat 1 in a fixed position on theseat 7. Also in this case, by pulling aportion 18 of thebelt 62, a tensile force is applied on thebelt 62 in order to render the position of thesafety seat 1 stable and secure. - In both cases, shown in
FIGS. 1 and 5 , theregulator 19 is without structural elements, retention elements, and guide elements made of plastic material: in fact, thecross member 49 is made of a single piece with theplate 35, on the one hand, and thecross member 53 is made of a single piece with theportion 55, on the other hand. In this way, high levels of reliability and safety, as well as a high level of simplicity of installation, are achieved. Obviously, a covering made of plastic material could be provided, but only having an aesthetic function. - As has been mentioned above, the
opening 48 enables theportion 14 to be guided in a direction substantially parallel to thedirection 34 and theportion 18 to be kept folded on theedge 60 of thecross member 37 so that theportion 18 is withheld in a stable way by the nipping action exerted by thecross member 53 even when thebelt 9 is not perfectly tensioned. - Finally, it is clear that modifications and variations may be made to the
regulator 19 described herein with reference to the attached figures, without thereby departing from the sphere of protection of the present invention, as defined in the annexed claims. - In particular, the shape of the
portion 54 could be different; and/or the relative position between thecross members portion 18 around thecross member 53 could be reversed with respect to the one described above; and/or the function of thrust of thecross member 53 in its advanced position towards thecross member 37 could be performed by a system different from thesprings 45; and/or thecross member 21 could be replaced by a tab, which can be connected to an engagement device of the safety belt.
