Abstract

A vehicle occupant safety apparatus (10) for helping to protect an occupant of a vehicle (12) having a side structure (16) comprises an inflatable vehicle occupant protection device (14). The protection device (14) has a deflated condition and has an inflated condition in which the protection device is inflated between the occupant and the vehicle side structure. The safety apparatus (10) also comprises an inflator (22) for providing inflation fluid for inflating the protection device (14), and a fill tube (20) for directing inflation fluid into the protection device. The apparatus further comprises a support (60) for supporting the inflator (22) and the fill tube (20) relative to each other. The support (60) has a fluid flow passage (210) for directing inflation fluid from the inflator (22) to the fill tube (20). In a preferred embodiment, the support (60) comprises a clamp having a first portion clamped on the inflator (22) and a second portion clamped on the fill tube (20).

Claims

1. An apparatus for inflating an inflatable vehicle occupant protection device, said apparatus comprising:

an inflator for providing inflation fluid for inflating said protection device;

a fill member for directing inflation fluid into said protection device; and

a clamp for connecting said inflator with said fill member, said clamp having a first portion which clamps on said inflator, a second portion which clamps on said fill member, and a fluid flow passage extending between said first and second portions of said clamp for directing inflation fluid from said inflator to said fill member.

2. An apparatus as set forth in claim 1 wherein said clamp comprises first and second clamp parts clamped together on said inflator and on said fill member.

3. An apparatus as set forth in claim 2 wherein each one of said first and second clamp parts defines a respective fluid flow area in said clamp, said fluid flow areas together forming said fluid flow passage for directing inflation fluid from said inflator to said fill member.

4. An apparatus as set forth in claim 1 wherein said inflator has an inflation fluid outlet which opens into said fluid flow passage and said fill member has an inflation fluid inlet which opens into said fluid flow passage.

5. An apparatus as set forth in claim 1 wherein said inflator and said fill member extend through said fluid flow passage in said clamp, said clamp including first and second clamp parts clamped together on opposite sides of said inflator and on opposite sides of said fill member.

6. A vehicle occupant safety apparatus for helping to protect an occupant of a vehicle having a side structure, said safety apparatus comprising:

an inflatable vehicle occupant protection device having a deflated condition and having an inflated condition in which said protection device is inflated between the occupant and the vehicle side structure;

an inflator for providing inflation fluid for inflating said protection device;

a fill tube for directing inflation fluid into said protection device; and

a support for supporting said inflator and said fill tube relative to each other, said support comprising a clamp having a first portion clamped on said inflator and a second portion clamped on said fill tube, said support having a fluid flow passage for directing inflation fluid from said inflator to said fill tube.

7. An apparatus as set forth in claim 6 wherein said clamp comprises first and second clamp parts clamped together on opposite sides of said inflator and on opposite sides of said fill tube.

8. An apparatus as set forth in claim 7 wherein each one of said first and second clamp parts defines a respective fluid flow area in said clamp, said fluid flow areas together forming said fluid flow passage for directing inflation fluid from said inflator to said fill tube.

9. An apparatus as set forth in claim 6 wherein said inflator has an inflation fluid outlet which communicates with said fluid flow passage and said fill tube has an inflation fluid inlet which communicates with said fluid flow passage.

10. An apparatus as set forth in claim 9 wherein said inflator and said fill tube extend through said fluid flow passage in said support.
