Description

SEAT BELT PRESENTER
The present invention concerns a seat belt presenter and especially a seat belt presenter for seat belts located in a rearward position.
In motor vehicles with two passenger doors and four or five seating positions, the front seat belts are located in a rearward position with respect to the front seats to allow easy access to the rear seats. Generally the lower fixing point of the shoulder section of the seat belt slides on a rod fixed to the floor of the vehicle, as shown in Fig. 1 , and moves from the rearward position, which it occupies with the seat belt out of use, to a forward position when the seat belt is in use. This results in a difficult access to the buckle tongue when it is in the rearward position.
The solutions proposed contemplate the use of so-called "presenting" devices that bring forward the seat belt and the buckle tongue, to facilitate gripping by the user. The known seat belt presenters are of an electric or mechanical type. They are fixed to the car body and are made up of numerous assembled parts which, even in the case of mechanical and non electric seat belt presenters, involve high production costs.
What is needed is a seat belt presenter to facilitate gripping of the seat belts which is inexpensive, easy to produce and to use, reliable, and which does not interfere with the fastening and the release of the buckle tongue in the buckle. Such a seat belt presenter is provided according to the attached claim 1.

Detailed Description of the Invention
In the figures a seat belt presenter 1 according to the invention comprises a base portion 2, generally made of a plastic material. The base portion of the seat belt presenter is provided with a loop or slot 2a through which the webbing 4 of a seat belt passes. The dimensions of the slot 2a and of the base portion 2 are such as to allow easy sliding of the seat belt presenter 1 along the webbing 4 of the seat belt, similar to what happens to the buckle tongue 6.
A handle 5 is fixed to the base portion 2, extending from the base portion 2 in the direction of intended movement of the seat belt, indicated with letter F in the figures. In other words, the handle 5 extends towards the front of the car. As shown in Figs. 1 and 3, the handle acts as an element for pulling the webbing of the seat belt, that is as an element which is gripped instead of the webbing itself or instead of the buckle tongue 6. For this purpose the length of the handle 3 is such as to allow the user to grip it easily. In the figures the handle 5 and the base portion 2 that slides on the webbing are positioned below the buckle tongue 6 and preferably above a blocking element or button B. The blocking element or button B prevents the seat belt presenter from sliding to a lower portion of the webbing and keeps the seat belt presenter 1 in a position where it can be easily gripped. However it is possible to position the seat belt presenter above the buckle tongue, perhaps providing it with means for catching the buckle tongue and dragging it together with the seat belt presenter
The handle 5 is joined to the base portion 2 that slides on the webbing by a means for fastening the handle in a rotating manner to the base portion 2. Thus the handle is able to make at least a partial rotation of the base portion 2, and vice versa, after the handle has been gripped and pulled in the direction of intended movement of the seat belt. The handle 5 is preferably fastened to the base portion 2 in a central position, but it is possible for the fastening means between handle and base portion to be in a rearward position, that is on the opposite side with respect to that the handle 5 is extended.
An example of a rotatable fastening means in a rear position is shown in Fig. 2. In this embodiment the rotatable fastening means is a metal or plastic rod 21 that is engaged in a member 22 in the base portion 2 and is covered by a plastic coating 23, most of the remaining portion being made of an elastomeric material. The rod 21 is flexible, so as to allow by bending, a partial rotation between the handle and the base portion 2 and the webbing 4. In this way an angle is established between the handle and the base portion 2 that allows the webbing 4 of the seat belt to be unrolled easily and the buckle tongue 6 to be pulled forward into a position where it is gripped by the user, as shown in Figs. 3 and 4, and then engaged in the buckle 15, as shown in Fig. 5.
Fig. 6 shows an embodiment in which the rotatable fastening means is a hinge 8. The hinge 8 has a fixed portion 9 integral with the base portion 2, for example all in one piece with it, and a rotatable fastening portion 10 that is integral with the handle 5. In the embodiment shown in Fig. 6 the handle 5 is made of a plastic material, for example a soft-touch elastomer, molded onto a rigid element 11 , for example made of metal, and it forms an integral part with portion 10 of the hinge 8. The hinge 8 also comprises a spring (not shown) or similar elastic means which exert stress on the handle 5 towards the base portion 2 to ensure an elastic return of the handle towards the sliding base portion after its use. In the embodiment shown in Fig. 2 this effect is obtained directly by the elastic nature of the handle material.
The embodiment with a hinged restraint also comprises a means for limiting the angle of rotation between the handle and the buckle tongue. In the embodiment shown in Fig. 6 these means comprise of an element 12 protruding from the a rotatable fastening portion 10 of the hinge and comprising the end of the rigid element 11 , suitably curved after having passed through the a rotatable fastening element 10. In the embodiment with an elastically deformable handle shown in Fig. 2, the extent of the rotation is automatically limited by the nature of the elastomeric material comprising the handle.
The maximum angle of rotation that is formed between the handle and the buckle tongue is between 60 and 120 degrees, and preferably between 75 and 105 degrees. These angles allow the webbing 4 of the seat belt to slide without catching inside the slot 2a; with smaller or larger angles, the seat belt webbing gets stuck easily in the slot, making it difficult to move the seat belt forward.
Figs. 7, 7A and 8 show two embodiments of the seat belt presenter, which make it installable on already assembled seat belts. In the embodiment shown in Fig. 7 the sliding base portion is made of two U or C shaped elements 16, 17, provided with a male and female couplings 18 next to which the two U or C shaped elements are glued or welded to one another. In Fig. 8 the U or C shaped elements 16, 17 are joined together by two pairs of retaining screws 19. This embodiment, like the previous one in the case of glued U or C shaped elements, allows the seat belt presenter to be installed on seat belts that are already installed in the vehicle. Put another way, to provide a seat belt presenter on an already installed seat belt a pair of complementary elements (16, 17) are joined together to provide the slot for receiving the webbing of the seat belt therethrough.
The operation of the seat belt presenter will now be described with reference to the figures. Initially, as shown in Figs. 1 , 2 and 6, the device is adjacent to the base portion 2, generally in contact with it, alongside the seat 14. The handle 5 points towards the front of the vehicle and is gripped by the user who pulls it in the direction of desired movement of the seat belt, initially in the direction indicated by the arrow F. After pulling and the resistance of the webbing 4 of the seat belt, a rotation takes place between the handle and the base portion, which for an angle that varies according to the type of rotatable fastener used. In the embodiment with a hinge, the maximum angle of rotation is preferably about 80-85 degrees, as shown in Fig. 6. In the embodiment with an elastic handle fastened at the rear or in the center, the angle may be smaller, but in all cases there is a rotation, that is the formation of an angle between the base portion and the handle.
Thanks to the above-mentioned rotation, the base portion 1 goes into a position more or less transverse with relation to the direction indicated by the arrow F, allowing the necessary sliding of the webbing 4 of the seat belt in the slot 2a in the base portion.
The seat belt presenter is then taken to the opposite side of the seat 14 and the buckle tongue 6 is inserted in the retaining buckle 15. When the handle 5, 19 is released the handle is returned to the position adjacent to the base portion by the return spring in the embodiments with a mechanical hinge, or by the elasticity of the material of the handle 5 in the embodiment of Fig. 2.
The present invention offers numerous advantages with respect to the prior art seat belt presenters. In fact the invention allows the elimination of the presence of traditional seat belt presenters, with clear advantages in design and cost. At the same time, the seat belt presenter according to the present invention can be easily realised and has very low costs. Its simplicity of production results in high reliability of the device.
