Description
2335228 Seat Belt Safety Device The present invention relates to a safety
device for a vehicle seat belt buckle.
Many child seats nowadays involve the use of the seat belts with which the vehicle is fitted ordinarily for use by adults. However, often a child learns how to release the buckle of the seat belt by depressing the release button of the buckle, thus unfastening the belt: this can lead to dangerous consequences, either because the child is no longer restrained by the seat belt and may be thrown about within the vehicle, or because the driver will be distracted.
A number of devices have been proposed for fitting to the seat belt buckle and preventing the child gaining access to the release button of the buckle. However, these devices have suffered various drawbacks, in particular making it complicated for an adult to engage the buckle and/or difficult for the adult to release the buckle especially in the case of an emergency. I have now devised a safety device for a vehicle seat belt buckle, which overcomes the above-mentioned drawbacks. 20 In accordance with the present invention, there is provided a safety device for the buckle of a vehicle seat belt, the buckle comprising a tongue carried by the seat belt and a body part having a socket formed therein to receive the tongue, the buckle also having a release button which it depressible for releasing the tongue from the body part, the safety device comprising a cover element for overlying said release button of the buckle, said cover element being pivotable outwardly to gain access to said release button.
In use of this device, it is an easy matter for an adult to pivot the cover element of the device outwardly to gain access to the release button, then depress this button to release the buckle. However, it is difficult for a small child to reach down sufficiently far to grasp the cover element and pivot it outwardly, and additionally depress the release button: this is particularly the case where the cover element must be pivoted outwardly from its upper end because, even once 2 the cover element is pivoted outwardly, it still lies between the child and the release button. The device is therefore child-proof: the device also provides effective protection where the seat is used by a handicapped person.
The safety device may have an attachment portion for its attachment to the seat belt adjacent the tongue part of the buckle. The attachment portion perferably incorporate means for detachable attaching it to the seat belt. Preferably the attachment portion is formed with at least two transverse slots arranged for the seat belt to pass through successively, such that sliding movement of the device along the belt is frictionally resisted: at least one edge of at least one of these slots may be serrated or otherwise configurated to increase the resistance to sliding relative to the belt. The safety device may comprise a substantially rigid member, arranged to that as it is pivoted outwardly from the buckle body part, its attachment portion pivots inwardly, correspondingly deflecting the portion of the seat belt to which it is attached. 20 Alternatively, the cover element may be hinged relative to the attachment portion of the device. In this case, the device may be formed in one- piece from relatively rigid or inflexible sheet material, which is provided with at least one transverse fold to permit the cover element to hinge relative to the attachment portion.
The safety device may be arranged for use with a buckle which has the release button positioned in the top end of the body part of the buckle. In this case, and in one preferred embodimennt, the attachment portion of the safety device lies in a first plane, for engagement with the seat belt, and the cover element comprises a flap which lies in a second plane, spaced from the plane of the attachment portion, and connected to the attachnent portion by a transition portion: in use, the flap lies against or alongside the outer side of the buckle body part and the transition portion lies over the top end of the release button. In another preferred embodiment, the cover element may comprise a curved portion joined to the attachment portion and curved outwardly and downwardly and finally inwardly.
1 3 In another embodiment of safety device in accordance with the invention, the device is arranged to fit over the buckle body part and has a top portion which, in use, lies over the top end of the buckle body part but has an opening for insertion of the buckle tongue: the cover element is arranged to lie against the side of the body part, in which the release button is positioned, and is hinged relative to the top portion of the device. Preferably the device has a rear portion which lies against the rear of the buckle body part and carried an attachment portion for engaging a stalk or portion of seat belt on which the buckle body part is mounted.
In the above-described emdbodiments, the cover element may be f ormed with an aperture to enable an able adult to insert his or her finger(s) to depress the buckle release button: this may allow the buckle to be released more quickly, to free the child or handicapped person who is restrained by the seat belt, than either pivoting the cover element outwardly or sliding it slong the seat belt. The aperture may be arranged to prevent or substantially inhibit access to the buckle release button on the part of the child or handicapped person who is restrained by the seat belt: preferably an upper part of the cover element is closed, to close across the top of the body part of the buckle, and the aperture in the cover element is formed in a part of the cover element which extends down the side of the buckle body part.
Also, in accordance with the present invention, there is provided a safety device for the buckle of a vehicle seat belt, the buckle comprising a tongue carried by the seat belt and a body part having a socket f ormed in an end thereof to receive the tongue, the buckle also having a release button which is depressible for releasing the tongue from the bocy part, the safety device comprising a cover element for overlying the socket end and a side of the buckle body part, including its release button, the cover element being formed with an aperture to gain sidewise access to the buckle body part and to its release button.
Preferably, in each embodiment, at least the cover element of the safety device is of a transparent or semitransparent material, so that the buckle remains visible.
4 Embodiments of the present invention will now be described by way of examples only and with reference to the accompanying drawings, in which:
FIGURE 1 is a side view of a first embodiment of safety device in accordance with the present invention, shown fitted to a seat belt; FIGURE 2 FIGURE 3 safety device in FIGURE 4 safety device of FIGURE 5 of safety device FIGURE 6 15 safety device in is a front view of the device of Figure 1; is an isometric view of a second embodiment of accordance with the present invention; is a similar view of a modified form of the Figure 3; is a an isometric view of a third embodiment in accordance with the present invention; and is an isometric view of a fourth embodiment of accordance with the present invention.
Referring to Figures 1 and 2 of the drawings, there is shown a safety device 20 for a vehicle seat belt buckle 10,14. The buckle, in the example shown, comprises a body part 10 mounted to the upper end of a stalk 12, and a tongue 14 carried by the belt 16 and inserted downwardly into a socket formed in the top of the body part 10. The body part 10 houses a mechanism for locking the tongue 14 within its socket, and is furthermore provided with a button 18 which is depressible for releasing the tongue 14, thereby releasing the buckle.
The safety device 20 shown in Figures 1 and 2 is attached to the seat belt 16 just above the tongue 14 and includes a cover portion 24 for overlying the release button 18 when the tongue 14 is engaged with the body part 10 such that the belt 16 is in its normal, lightly-tensioned condition.
In particular, the safety device 20 comprises a onepiece member of plastics material, having a flat, generally rectangular portion 22 by which the device is attached to the seat belt 16, and a flat, generally rectangular portion 24 which lies in a plane substantially parallel to but spaced from the attachment portion 22: the two portions 22,24 are joined to each other by a curved transition 23. The cover portion 24 extends away from the attachment portion 22 in the longitudinal direction of the device. The attachment portion 22 is formed with two transverse slots 26 and with a slit 27 which extends longitudinally of the device from the free end edge of portion 22 to the inner of the two slots 26.
It will be appreciated that the slit 27 allows for insertion of the seat belt 16, in order to engage the belt to the device 20 such that (as shown) the belt 16 passes forwardly through the inner slot 26, then rearwardly through the outer slot 26. In this manner, the device 20 is frictionally engaged with the belt 16: although the device can be slid along the belt, it is relatively resistant to this movement. This resistance to sliding movement may be increased by providing serrations or otherwise configuring at least one edge of at least one of the slots 26.
It will also be appreciated that because, in use, the device 20 overlies the release button 18 of the seat belt buckle, the release button is not directly accessible for depression to release the buckle. However, the release button may be readily accessed by pivoting the cover portion 24 of the device away from the body part 10 of the buckle: the device 20 is a rigid member and this outward pivoting movement of the cover portion 24 produces corresponding inward pivoting movement of the attachment portion 22 and inward deflection of the belt 16, all shown by the arrows A in Figure 1. Whilst it is easy for an able adult to pivot the device and gain access to the release button in the manner just described, it is very difficult for a child or a handicapped person, who is restrained by the seat belt 16, to reach sufficiently far down to grip the device 20 and pivot it outwardly and upwardly, and additionally to press the release button, because all the while the device 20 still overlies and inhibits easy access, on the part of the child or person restrained by the seat belt, to the release button.
If desired, the device 20 may be slid along the belt 16 away from the buckle tongue 14, against the above-mentioned resistance to movement, before inserting the tongue into its socket in the body part 10 of the buckle, after which the device 20 may be slid along the belt in the opposite direction, to the position shown in Figure 1 in which it overlies the release button of the buckle. Similarly, when it is desired to release the buckle, the device 20 may be slid upwardly along 6 the belt in order to uncover the release button: however, a child or handicapped person would find it difficult to slide the device along the belt.
Figure 3 shows a safety device which is formed from a single sheet of relatively rigid or inflexible plastics material which has two transverse fold lines to provide an attachment portion 32, a cover portion 34 and an intermediate or transition portion 33. The attachment portion 32 is formed with two transverse slots 36 and a slit 37 corresponding to the slots 26 and slit 27 of the device 20 of Figures 1 and 2, enabling the device to be attached to a seat belt in the same manner. The device of Figure 3 is used similarly: however, to gain access to the buckle release button, it is only necessary to hinge the cover portion 34 outwardly, relying on the flexibility of either or both of the transverse fold lines of the device. This enables an adult to access the release button quickly and easily, but it still presents difficulties for a child or handicapped person.
Figure 4 shows a device which is the same as the device of Figure 3, except that the attachment portion 42 is formed with two transverse slots 46 extending from the opposite side edges of the device. The seat belt is, in use, engaged with the device in similar manner, i.e. by passing upwardly through one slot 46 and then downwardly through the second slot. it will be appreciated that other arrangements of slots, different from those shown in Figures 3 and 4, may be provided for attachment of the device to the seat belt.
Figure 5 shows a device which is arranged to fit over the body part of the seat belt buckle, and has a transverse slot 53 through which the tongue of the buckle can be passed for insertion into the socket in the body part. The device is formed from a piece of sheet plastics material and is formed with two transverse fold lines to provide a top portion 52 in which the slot 53 is formed, a front cover portion 54 and a rear panel 56. Two further transverse folds are provided, to form an attachment portion 58 and a narrow connecting portion 60, the attachment portion being formed with a transverse slot 59 and a slit 57 extending from the outer edge of the device to the slot 59.
1 7 In use, the device of Figure 5 fits over the body part of the seat belt buckle, with its attachment portion 58 engaged with the stalk or seat belt on which the body part of the buckle is carried. Further, the top portion 52 of the device lies across the top of the body part of the buckle and the cover portion 54 overlies the release button of the buckle. The buckle is fastened by passing the tongue of the buckle through the slot 53 of the device and into the socket in the body part of the device. In order to release the buckle, the cover portion is hinged outwardly to gain access to the release button of the body part of the buckle.
Figure 6 shows a safety device which comprises a onepiece member of plastics material, having a flat, generally rectangular portion 62 by which the device is, in use, attached to the seat belt: in particular, the portion 62 is formed with an arrangement of transverse slots 66 and a longitundinal slit 67, similar to the device of Figures 1 and 2; it may instead be formed with an arrangement of slots similar to the device of Figure 4. The device further comprises a cover portion 64 which extends from the lower edge of the attachment portion 62, the cover portion 64 curving outwardly and downwardly and finally inwardly. The cover portion 64 is formed with a window 65 the upper edge of which is spaced from the lower edge of the attachment portion 62. It will be appreciated that, in use of the device sh-).,m:n in Figure 6, the cover portion 64 overlies the top end and outer side of the buckle body, including its release button. The device thus prevents a child or handicapped person, who is restrained by the seat belt, from gaining direct access to the buckle release button. However, just in the same manner as for the device of Figures 1 and 2, an able adult is able to pivot the device outwardly and upwardly, about its point of attachment to the seat belt, in order to gain access to the buckle release button: alternatively, the able adult may be able to slide the device along the belt. Moreover, the device of Figure 6 offers the opportunity for the above adult, wishing to release the buckle and free the child or handicapped person with minimal delay, to insert his or her fingers through the aperture 65 and depress the buckle release button. It will be appreciated that 8 it is extremely difficult for the child or handicapped person, restrained by the seat belt, to reach downwardly over the top, closed part of the curved cover portion, then pass his f ingers inwardly through the aperture 65 and depress the buckle release button.
In all of the embodiments which have been described, the device is preferably formed of a transparent or semitransparent material, so that the buckle which underlies the device remains visible.
