Abstract

A belt adjusting device comprises a belt webbing having a free end and a tensioned section. The belt adjusting device further comprises a holding part provided with a through passage for a belt webbing and a contact surface adjacent to the through passage. The contact surface is inclined relatively to a plane in which the through passage extends. The belt adjusting device further comprises an arresting part which is movable relatively to the holding part and comprises a deflection web. The deflection web comprises a clamping surface on its side facing the holding part. The belt webbing runs through the through passage, around the deflection web and back through the through passage. The free end of the belt webbing passes through the through passage between an edge of the through passage adjacent the contact surface and the tensioned section of the belt webbing.

Claims

1. A belt adjusting device for a vehicle safety belt system having a belt webbing with a free end and a tensioned section, said belt adjusting device comprising:

a holding part having a through passage through which the belt webbing extends and a contact surface adjacent said through passage, said contact surface extending in a first plane which extends at an angle of approximately 15°

to a second plane in which said through passage extends;

an arresting part which is movable relative to said holding part, said arresting part having a deflection web and a supporting section, said deflection web having a clamping surface facing said holding part and extending in a third plane, said supporting section extending in a fourth plane which extends at an angle between approximately 160° and

approximately 175°

to the third plane, whereby the belt webbing is adapted to run through said through passage, around said deflection web, and back through said through passage so that the free end of the belt webbing is adapted to pass through said through passage between an edge defining the through passage adjacent said contact surface and the tensioned section of the belt webbing.

2. A belt adjusting device for a vehicle safety belt system comprising a belt webbing having a free end and a tensioned section, a holding-part provided with a through passage for said belt webbing and a contact surface adjacent to said through passage, said contact surface extending in a first plane and being inclined relatively to a second plane in which said through passage extends by an angle of approximately 15°

, and an arresting part which is movable relatively to said holding part and comprises a deflection web, said deflection web comprising a clamping surface arranged on a side facing said holding part and extending in a third plane, said arresting part further comprising a supporting section, said supporting section and said clamping surface extending in fourth and third planes, respectively, said third and fourth planes being inclined with respect to each other by an angle between approximately 160° and

approximately 175°

on a side facing away from said holding part, said belt webbing running through said through passage, around said deflection web and back through said through passage, said free end of said belt webbing passing through said through passage between an edge of said through passage adjacent said contact surface and said tensioned section of said belt webbing.

3. The belt adjusting device of claim 2, wherein said contact surface is provided with a structure which increases friction.

4. The belt adjusting device of claim 3, wherein said contact surface is corrugated.

5. The belt adjusting device of claim 2, wherein said clamping surface is provided with a structure which increases friction.

6. The belt adjusting device of claim 5, wherein said clamping surface is corrugated.
