Definitions

  • the invention relates to a fastener for adjusting belt straps, in particular seat belt straps, comprising a housing having a substantially U-shaped cross section, the web part of which is formed with cross bars and an adjustable belt webbing being wrapped around one of them, and comprising a pivotally mounted on the legs of the housing Cover part with a clamping lug wrapped by the adjustable belt strap, which in the closed position interacts with the edge of a crossbar of the housing in order to lock the adjustable belt part by clamping.
  • Clasps of this type have the task of enabling a quick adjustment, for example, of a motor vehicle seat belt for children to the body dimensions of the child to be secured, and yet of ensuring a secure and unrelenting transmission of the belt forces.
  • Such a closure is known for example from DE-U-84 28 866.
  • a housing made of sheet metal and U-shaped cross-section is used, on the legs of which a cover part made of plastic is articulated.
  • it has molded bearing journals that can be snapped into corresponding bores in the legs of the housing.
  • the adjustable belt part is wrapped around a web-like clamping lug of the cover part, the free end of the adjustable belt part being first pulled through this recess through a recess in the web part of the housing and after being wrapped around the clamping lug.
  • Clamping lug interacts with an edge of the recess in the web part of the housing, which causes the belt strap to be fixed by clamping.
  • both the housing and the cover part are made of plastic, that the web part of the housing is reinforced by a metal insert frame absorbing the tension forces of the webbing and that the cover part has a design that is at least in the locking position results in a positive connection in the pulling direction of the webbing between the cover part and the housing.
  • the closure can be manufactured very economically, since the housing and cover part can be produced by injection molding and the insert frame can be manufactured as a simple, flat sheet-metal stamped part. It can also be injected as an insert into the molded housing part.
  • the cover part is automatically brought into the closed position when the webbing is under tensile stress.
  • the opening angle of the cover part is limited to a maximum of approximately 45 ° by a stop.
  • an inhibition can be provided on the cover part and / or on the housing, which prevents the cover part from opening against a defined force. This inclination can be effectively prevented by providing the cover part with lateral gripping surfaces for grasping and holding the opened fastener when adjusting the webbing.
  • the handling during adjustment can be improved in that the free end of the adjustable webbing points in the direction of the non-adjustable webbing.
  • the closure according to the invention consists of a housing 1 of U-shaped cross section, the web part 2 of which is reduced to cross bars 4 and 5 by a recess 3 in the manner of a buckle.
  • the web part 2 is reinforced by a metal insert frame 6 injected into it, which relieves the cross bars 4 and 5 with regard to their stress.
  • a cover part 8 is pivotally mounted in a suitable manner and secured by a stop (not shown) in such a way that pivoting by approximately 45 ° is possible.
  • the lid part 8 has two side cheeks 9 which, by means of a grip tongue 10 and with three mutually parallel webs 11, 12 and 13, form a frame with spaces formed between the webs, the web 12 functioning as a clamping lug.
  • the grip tongue 10 is provided with lateral grip surfaces 14 designed to be grippy by means of projections 14a.
  • the areas of the gripping surfaces 14 have a width dimension that goes beyond the width dimension of the cheeks 9 and essentially corresponds to the width dimension of the legs 7. In this way, the gripping surfaces 14 are quasi components of the legs 7, which they join, however, via a gradation which, in the pulling direction of the webbing, results in a positive or smooth transition from the housing 1 to the cover part 8 in the locking position of the latter
  • a webbing 15 is firmly attached to the housing 1 by looping the free end of the webbing 15 through the recess 3 in the web part 2 of the housing 1 around the cross bar 5 and sewing the loop 16 formed in a suitable manner becomes.
  • An adjustable webbing 17 is then with its free end 18 with the lid part 8 in the open position also through the recess 3, but then between the webs 12 and 13 of the lid part 8, around the web 12 and between the webs 11 and 12 again pushed through the recess 3 Then the free end 18 is passed between a web-shaped end panel 19 on the housing 1 and its cross member 4, then guided around the outside of the web 11 and finally through a passage 20 between the web 13 and the handle 10 and under this led out through.
  • the belt guide described has the effect that, when a tensile load on the belt parts 15, 17 and 18 takes effect, a torque acts on the opened cover part 8, which causes the cover part 8 to move into the locking position between the web 12 of the cover part 8 and the cross member 4 of the housing 1 clamped and thus locked, the clamping force being stronger, the greater the tensile stress acting on the belt parts 15 and 17.
  • the cover part 8 When adapting the belt to the body dimensions of the person to be secured, the cover part 8 is brought into the open position, so that the aforementioned clamping is released. In this position, the adjustment can be made by pulling on the free end 18 of the adjustable webbing 17 or on the webbing 17 even while holding back the cover part 8.
  • a detection of the closure on the grip surfaces 14 of the cover part 8 is expedient, in particular in the case of an adaptation by extension, since this prevents the inhibiting forces occurring during this process from moving the cover part 8 into the locking position.
  • the lateral gripping surfaces 14 are preferably curved outward.
  • one or more, e.g., between the legs 7 of the housing 1 and the cheeks 9 of the cover part 8 knob-like latching formations 19 may be provided in order to additionally secure the closed position of the cover part.
