Claims17
A cover for a seat belt tongue, comprising:
- an elastically deformable body configured to hold the cover onto the seat belt tongue;
- and
- a webbing engagement projection configured to contact seat belt webbing, and to provide a resistance to drawing of the seat belt webbing through the seat belt tongue,
- wherein the webbing engagement projection projects from a surface which is substantially parallel to a seat belt tongue extension configured to be inserted into a buckle for fastening the seat belt tongue,
- wherein a cross section of the webbing engagement projection comprises a narrower portion configured, in use, to lie close to a webbing slot in the seat belt tongue through which the seat belt webbing passes, and a wider portion disposed further away from the webbing slot than the narrower portion, such that the webbing engagement projection in cross section tapers between the narrower portion and the wider portion, and
- wherein, in use, the webbing engagement projection serves to narrow a range of angles through which the seat belt webbing is passed unhindered through the webbing slot.
