Definitions

  • the present invention relates to a buckle arrangement and more particularly to an arrangement for use with automobile buckles for rear passenger seats, and to a mounting arrangement therefor.
  • rear safety restraint buckles To provide the required security and strength when restraining an occupant, rear safety restraint buckles must be attached to fixed parts of a vehicle rather than to elements of the seat. Rear seat buckles are thus usually attached to the vehicle support structure underneath the seat cushion or squab in the central region thereof. The buckles then lie on seat squabs and a rear passenger must pick up the buckle head to correctly orient it to insert into it the engaging tongue on the end of the cooperating belt. This is obviously undesirable from a convenience point of view. Also, the buckles tend to slip down between the seat cushions.
  • the rear seat can be folded so as to expand the rear area available for storage in the car. This is particularly so of so-called hatchback cars. It is usually effected by pivoting the base part of the rear seat, otherwise known as the squab, into a vertical position and folding the back seat support downwardly in a forward direction so that it adopts a horizontal position.
  • the rear seat squab is in two parts to enable, for example, one half to be folded to provide extra storage while still retaining a single rear passenger seat.
  • the buckles are often located between the seat cushions but the same problem arises when folding the seat cushions back into the seating position.
  • Prior known rear seat buckle arrangements also tend to sit undesirably high above the seat, making the seat uncomfortable for a third passenger.
  • the present invention aims to provide an arrangement which obviates these disadvantages by causing a buckle head to be automatically located in a convenient position and orientation and which automatically tends to present itself with its tongue receiving opening facing in the tongue insert direction when the seat squab is in or returns to a horizontal position.
  • a further object is to provide a shorter rear seat buckle head mounting assembly.
  • an arrangement comprising a safety restraint buckle head having an opening formed therein for receipt of a cooperating safety restraint engaging member, means for securing the buckle head to a fixed part of a vehicle, and means for orienting the buckle head opening in a substantially predetermined direction and orientation to present the buckle head in a generally upward direction and in an orientation substantially parallel to that of the cooperating member in normal use so as to facilitate insertion of the cooperating engaging member.
  • the most convenient orientation for a vehicle occupant who is engaged in fastening his safety restraint is for the opening to be generally parallel to the side of the vehicle and to be facing upwardly and slightly forwardly.
  • the buckle head is mounted on a support block attached to a fixed part of the vehicle and spring tensioning means are provided between the buckle head and the support block so that the buckle head is resiliently retained in a generally vertical orientation.
  • the spring tensioning may be effected by a helical return spring wound around a support bar which forms an intermediate member between the buckle head and the support block. Additionally a spring clip may be used to provide further resilient biasing force.
  • the buckle is supported on the support block via a ball joint and is tensioned in a vertical direction by a compression spring acting between the buckle head and the support block.
  • a compression spring acting between the buckle head and the support block.
  • the spring is covered by a shroud, which may be of plastic or of fabric, for protection from dust, dirt and any loose items in the vehicle.
  • the buckle head may be supported on a rigid stalk which passes through an aperture in the support block and which is connected to the support block by a flexible webbing.
  • a suitable resilient bias whilst allowing adequate lateral movement of the buckle for adjustment to different occupant sizes and shapes, and ensuring a strong connection to the vehicle, could be used and will be evident to a person skilled in this field without further inventive input.
  • one embodiment of the present invention provides for a guide channel to be cut or moulded or otherwise defined or formed in a seat squab.
  • This guide channel preferably has a profile providing a guide path for the buckle head, which rises in a curve from the bottom rear edge of the seat squab to the top a short distance forward of the rear edges.
  • the buckle head rides up the channel and is thus turned from a horizontal position when it is lying on the seat support beneath the seat squab, into a generally vertical position as the seat squab is pushed fully into position.
  • the buckle head thus presents an opening for the cooperating part of the safety restraint, ie for the safety belt tongue, which is automatically located in a convenient position for the passenger.
  • the profiled channel has a tapering width as it rises through the seat squab so that as the buckle head rises it is turned through approximately 90 degrees, to align the opening for the tongue, not only vertically but also in a plane lying generally front to back of the vehicle. This is the most convenient orientation for the buckle head opening for insertion of a safety restraint tongue and also for operation of the buckle release button.
  • the buckle is flexibly connected to the vehicle chassis by means of a flexible fabric, such as seat belt webbing, fastened with a bolt.
  • the buckle head is resiliently biased to an upright position, preferably by a compression spring and the buckle is fastened securely to a part fixed to the vehicle by a length of flexible seat belt webbing, preferably two layers.
  • the webbing may be bolted to a mounting bracket comprising a metal plate with side flanges to provide a hollow gap below the plate.
  • the webbing passes through a slit in the plate or a recess in the side and is bolted or screwed to the bracket.
  • the double webbing may be stitched across the width of the webbing, in two or more generally parallel lines or zig-zag or other pattern.
  • a pin of metal or other suitable strong material may be positioned across the width of the webbing in the vicinity of the stitches, to resist twisting of the webbing.
  • Two buckles may be connected to the same mounting plate, and joined at opposite ends of the same length of single or double webbing. This has the advantage that stitch patterns are hidden beneath the mounting bracket and the overall height of the buckle head from the floor pan is thus not limited by the provision of stitch patterns nor by the sill end bracket.

  • a seat belt webbing 4 is connected to a belt tongue 5.
  • the belt tongue is insertable into the opening at the top of the belt buckle and release button 6 is operable to disengage the tongue from the buckle head.
  • the buckle head 2 is fixed via support rod 7 and support block 8 to an immovable part of the vehicle such as some part fixed to the chassis, by bolt 9.
  • Two return springs 10 and 11 are used to provide a bias to the buckle head to keep it in a generally upright orientation with the opening in the buckle head presented towards and in line with the tongue 5 so that the tongue may be easily inserted into the buckle by an occupant of the seat 1.
  • the spring 11 is covered by a protective shroud 12 (shown part cut away in Figure 1) .
  • FIG. 2 illustrates the buckle and supports as shown in Figure 1 but with the buckle head cover 3 and the spring cover 12 intact. However buckle head cover 3 is shown specially shaped to prevent fouling on the slider bar. This shaping is indicated at 13.
  • FIG. 3 shows another embodiment of the invention in part cut away view.
  • a buckle head 2 is supported on a shaft which ends in a ball joint 14.
  • the shaft passes through a support plate 15 which is bolted to the chassis or other immovable part of the vehicle by bolt .
  • the ball joint arranged in this way allows free movement of the buckle head and some possibilities are shown in Figure 4a (lateral movement) and 4b (forward/rearward movement) .
  • a coil spring 16 which tensions the buckle head in a generally vertical direction away from the support plate 15. This tension acts against the gravity of the buckle head 2 to maintain the buckle head in a upright generally vertical position presenting its opening towards the tongue 5.
  • the coil spring 16 is covered by a shroud 17 of a standard concertina-type profile which may be of plastics material or of leather or of fabric depending upon the requirements of matching the internal decor of a vehicle.
  • FIG. 5 illustrates a further alternative embodiment i of the invention. Again a coil spring is used and is wound around the shaft from the buckle head. However, the shaft terminates at a ring 17 below a support plate 15. Through the ring 17 passes webbing fabric 19 which is fastened to the support plate by nut 18 and washer plate 20.
  • Coil spring 16 again tensions buckle head 2 against support plate 15 and is protected by shroud 12.
  • FIG. 6 illustrates the underside of support plate 15 and like parts are referenced accordingly.
  • FIG 7 illustrates seat squab 1, i.e. the base cushion, and seat back 21 as the seat squab is being restored to the stowed position is which a vehicle occupant can use it as a seat.
  • the seat squab 1 is being moved in the direction of arrow 22 so as to bring it up against seat back 21.
  • the belt buckle 1 is lying on the seat support in a generally horizontal position.
  • the buckle head 2 is flexibly connected to anchorage point 23 by webbing 19 which is covered in a plastic protective shroud
  • Anchorage point 23 comprises a bolt 9 connected to the chassis or immovable part of the vehicle.
  • a seat squab 1 contains a cut out profiled scoop or channel 25 .
  • Figure 8 illustrates the same components when the seat squab 1 is moved fully up against seat back 21 in the stowed position. In this position, the buckle head 2 has caught in the channel 25 and been directed into a generally upright orientation with the buckle opening 26 presented to tongue 5 in the most suitable and convenient orientation for a vehicle occupant to fasten his or her seat belt.
  • the profiled scoop or channel 25 is specially shaped, for example tapered, towards its upper edges. It may be formed by appropriately moulding the seat, by cutting out from the body of the seat or by inserting specially shaped plastics panels .
  • the shape of the channel is such that it comprises a flat rearward part 27 and a twisted side part 28. The twisted side part guides the outer (near side in Figures 7 and 8) part of the buckle head and causes it to twist into the position shown in Figure 8.
  • Figures 9a to 9d illustrate schematically and in cross- section one way of arranging a rear passenger seat so as to make more rear storage space.
  • Figure 9a illustrates the seat squab 1 in a horizontal position and the seat back 21 in a generally vertical position in the normal stowed orientation for accommodating a passenger.
  • Figure 9b shows the seat squab 1 having been moved forward in the direction of arrow 29 away from seat back 21. The seat squab 1 is then rotated through 90° into an upright position as shown in Figure 9c and subsequently the seat back 21 is rotated into a horizontal position as shown in Figure 9d.
  • two buckle heads 2 are connected together via doubled webbing 25.
  • the webbing 25 passes under mounting bracket 26 and is fixed thereto, and to a fixed part of the vehicle by bolt 27.
  • the webbing 25 is stitched at 28, transversely, either in straight lines or using a zig-zag stitch as shown or in any other stitch pattern. This improves the strength of the connection between the buckle heads.
  • a webbing pin 29 extends across the width of the webbing to prevent twisting or puckering of the webbing. This may suitably be of 8.0mm diameter but the actual value chosen will depend on the geometry of the buckles, mounting plates and webbing. This is shown in the cut-away portion of Figure 11 for one buckle head but applies equally to both buckle heads.
  • a compression return spring 30 is attached between the upper surface of the mounting bracket 26 and a side flange spring holder 31 on the buckle head. This spring biases the buckle heads 2 to upright position for an easier insertion of the engaging tongue. Such a return spring is provided for both buckle heads.
  • the arrangement causes a gap between the two webbing fabric bonds as shown at 32.
  • the buckle head can pivot 180° in any direction and yet still conveniently presents the tongue receiving slot upwards for easy tongue insertion.
  • the return spring ensures that the buckle head returns to the position shown in the Figures.
  • This flexing buckle assembly can be constructed more compactly than was hitherto possible, i.e. shorter and closer to the seat itself, possibly as short as 25mm. In previous designs the height was governed by the sill end bracket and had to allow extra webbing space for stitch patterns .

Abstract

L'invention porte sur un montage de boucle pour siège arrière d'automobile comportant une tête de boucle (2) pourvue d'une ouverture destinée à recevoir une languette concourante (5) ainsi qu'un organe visant à orienter la tête dans une direction et selon une orientation prédéterminées de manière à faciliter l'insertion de la languette (5). La tête de boucle (2) est, de préférence, sollicitée de façon élastique (10, 11) pour s'orienter sur un plan vertical dans l'ensemble, son ouverture se trouvant généralement placée dans le sens de la longueur du véhicule afin d'être en parallèle avec la languette en utilisation normale. L'organe de sollicitation peut être un ressort hélicoïdal (16) enroulé autour d'une barre de support attachée à un élément de montage. La tête de boucle (2) peut être rattachée à la barre de support (7), elle-même boulonnée au châssis du véhicule. Elle peut, selon une variante, être montée sur une connexion à rotule (14) attachée à une plaque de montage (15), ou fixée par une longueur de sangle de la ceinture de sécurité. Il est possible de réunir deux boucles de ceinture de sécurité (2) à l'aide de deux épaisseurs de sangle (25), cousues de préférence, rivetées ou boulonnées à une patte de montage (26). Cet agencement garantit que les boucles arrière se présentent commodément à l'insertion de la languette, ne se trouvent pas facilement prises sous les coussins du siège arrière ou entre eux et, malgré tout, occupent un minimum d'espace, notamment pour ce qui est de leur hauteur de dépassement du siège.
