Abstract
Abstract The invention provides an apparatus for automatically moving the tongue of a seat belt into a position in which it may conveniently be grasped by an operator for insertion into a buckle. The apparatus comprises an inflatable bellows engageable with the tongue and extensible into the position by the application of pressure. The bellows may be retracted by vacuum pressure or by integral resilient means in response to the tongue having been inserted into the buckle.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
An apparatus for automatically moving the tongue of a seat belt from a storage position within an automotive vehicle to a position for convenient manual insertion into a buckle, comprising: a seat belt including tongue means movable between a retracted position and an extended position; inflatable means connectible to a source of pressure for movement between a retracted storage condition and an extended condition; means for operatively connecting the inflatable means and the tongue means at least during movement from the retracted condition to extended condition for moving the tongue to the extended position; and means for controlling the movement of the inflatable means such that in its extended condition it puts the tongue substantially into the position for convenient manual insertion into the buckle.
Claim 2
Independent Claim
125 words
An apparatus for automatically moving the tongue of a seat belt from a storage position within an automotive vehicle to a position for convenient manual insertion into a buckle, comprising: a seat belt including tongue means movable between a retracted position and an extended position; inflatable means connectible to a source of pressure for movement between a retracted storage condition and an extended condition; means for operatively connecting the inflatable means and the tongue means at least during movement from the retracted condition to extended condition for moving the tongue to the extended position; and means for controlling the movement of the inflatable means such that in its extended condition it puts the tongue substantially into the position for convenient manual insertion into the buckle.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein the inflatable means comprises a collapsible bellows which in its extended condition assumes an elongated configuration.
Claim 4
Dependent Claim
32 words
The apparatus of claim 2, wherein the bellows comprises first and second ends, the first end being affixed to the automotive vehicle and the second end comprising means for engaging the tongue.
Claim 5
Dependent Claim
35 words
The apparatus of claim 3 wherein the seat belt comprises a retractor and a deflector positioned between the retractor and the tongue, and wherein the first end of the bellows is affixed adjacent the deflector.
Claim 6
Dependent Claim
20 words
The apparatus of claim 4, wherein the deflector and the bellows are affixed to a door post of the vehicle.
Claim 7
Dependent Claim
33 words
The apparatus of claim 2, wherein the bellows is preformed such that in its extended condition it assumes a curved configuration for moving the tongue into the position for insertion into the buckle.
Claim 8
Dependent Claim
31 words
The apparatus of claim 6, wherein the bellows comprises a plurality of wall members and wherein the curved configuration of the extended bellows is imparted by wall members of different thicknesses.
Claim 9
Dependent Claim
29 words
The apparatus of claim 6 wherein the bellows comprises a plurality of wall members of different stiffnesses for imparting the curved configuration to the bellows in its extended condition.
Claim 10
Dependent Claim
14 words
The apparatus of claim 2, wherein the bellows comprises a plurality of support rings.
Claim 11
Dependent Claim
26 words
The apparatus of claim 9, wherein at least one of the rings comprises means for guiding the tongue into a position for insertion into the buckle.
Claim 12
Dependent Claim
32 words
The apparatus of claim 3, wherein the means for engaging the tongue comprises means for sliding along the belt between an inoperative position and a position in which it engages the tongue.
Claim 13
Dependent Claim
33 words
The apparatus of claim 1, wherein the source of pressure comprises a pump responsive to closure of a switch for providing pressure to the inflatable means for moving it to its extended condition.
Claim 14
Dependent Claim
24 words
The apparatus of claim 12 wherein the pump also provides vacuum pressure for deflating the inflatable means for returning it to its retracted condition.
Claim 15
Dependent Claim
