Seat-belt apparatus

A seat-belt apparatus for a vehicle seat comprising:

• a seat-belt retraction mechanism which is to be mounted on a vehicle door adjacent said seat,
• means coupling said seat-belt to the retraction mechanism to permit withdrawal of the seat-belt from the retraction mechanism,
• inertia-responsive means for inhibiting withdrawal of the seat-belt from the retraction mechanism whenever the inertia-responsive means is subjected to an acceleration in excess of a predetermined magnitude,
• means to mount said inertia-responsive means on said vehicle door,
• and means for responding to the position of said vehicle door to permit operation of said inertia-responsive means only when the vehicle door is closed, said inertia-responsive means including mens for permitting withdrawal of the seat-belt from the retraction mechanism at all times when said vehicle door is closed except when said inertia-responsive means is subjected to said predetermined acceleration.

A seat-belt apparatus of the kind which is arranged to be mounted in a vehicle for automatically moving a seat-belt of the apparatus into, and away from, an operative position across a vehicle seat comprising,

• a seat-belt retraction mechanism mounted on a vehicle door adjacent said seat,
• means coupling said seat-belt to the retraction mechanism to permit withdrawal of the seat-belt from the retraction mechanism, the retraction mechanism including a locking mechanism for inhibiting withdrawal of the seat-belt from the retraction mechanism when the retraction mechanism is subjected to an acceleration in excess of a predetermined magnitude,
• means for controlling operation of the locking mechanism in accordance with the position of said door to prevent operation of the locking mechanism whenever the door is open and to permit operation of the locking mechanism whenever the door is closed, said locking mechanism including means for permitting withdrawal of the seat-belt from the retraction mechanism at all times when the vehicle door is closed except when the retraction mechanism is subjected to said predetermined acceleration,
• a support mounted on said door adjacent a rear edge of the door, the support defining a guideway which is to extend in a substantially vertical direction in the vehicle,
• an anchorage which is to be slidably mounted in the guideway and includes means in which the seat-belt is to be slidably mounted, and
• means for adjusting the position of the anchorage along the guideway.
