Abstract
Abstract An automotive vehicle seat belt is attached to a slide mechanism attached to the vehicle body or door adjacent the occupant seat. The belt is connected to a slide element which slides on a rail between a forward released position (door open) and a rearward retaining position (door closed) in response to a door switch. A control mechanism overrides the effect of the door switch under certain conditions so that the belt does not release automatically when the door is opened. Examples of such conditions include specified criteria, ignition switch, transmission shift position, clutch position, and hand brake position.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
233 words
An automotive vehicle seat belt device, comprising: (a) a slide mechanism fixed to the vehicle, said mechanism comprising: (i) a slide rail; and (ii) a slide element slidably mounted to said rail; (b) a seat belt anchored at one end thereof to the vehicle and connected at the other end thereof to said slide element; (c) a drive motor operably connected to said slide element to move said slide element along said slide rail; and (d) an electric circuit for controlling the operation of said drive motor, comprising: (i) a front travel limit switch operative in response to the position of said slide element; (ii) a rear travel limit switch operative in response to the position of said slide element; (iii) a door switch operative in response to the door position; (iv) first changeover means responsive to a first position of said door switch and a switch for driving said motor in one direction to move said slide element to the front; (v) second changeover means responsive to a second position of said door switch and a first position of said rear travel limit switch for driving said motor in the reverse direction to move said slide element to the rear; and (vi) control switching means for disabling the effect of the movement of said door switch to its first position, said control switching means being actuated in response to predetermined vehicle conditions.
Claim 2
Dependent Claim
233 words
An automotive vehicle seat belt device, comprising: (a) a slide mechanism fixed to the vehicle, said mechanism comprising: (i) a slide rail; and (ii) a slide element slidably mounted to said rail; (b) a seat belt anchored at one end thereof to the vehicle and connected at the other end thereof to said slide element; (c) a drive motor operably connected to said slide element to move said slide element along said slide rail; and (d) an electric circuit for controlling the operation of said drive motor, comprising: (i) a front travel limit switch operative in response to the position of said slide element; (ii) a rear travel limit switch operative in response to the position of said slide element; (iii) a door switch operative in response to the door position; (iv) first changeover means responsive to a first position of said door switch and a switch for driving said motor in one direction to move said slide element to the front; (v) second changeover means responsive to a second position of said door switch and a first position of said rear travel limit switch for driving said motor in the reverse direction to move said slide element to the rear; and (vi) control switching means for disabling the effect of the movement of said door switch to its first position, said control switching means being actuated in response to predetermined vehicle conditions.
Claim 3
Dependent Claim
41 words
The seat belt device according to claim 1, wherein said control switching means is actuated by a transmission shift lever thereby to shut off the drive electric current flowing through said motor when said transmission shift lever is in reverse position.
Claim 4
Dependent Claim
36 words
The seat belt device according to claim 1, wherein said control switching means is actuated by a backup light to shut off the drive electric current flowing through said motor when the backup light is lighted.
Claim 5
Dependent Claim
45 words
The seat belt device according to claim 3, wherein said control switching means includes switching means closed in response to the lighting of the backup light and a normally closed switch opened in response to the closing of said switching means for disabling the motor.
Claim 6
Dependent Claim
28 words
The seat belt device according to claim 1, wherein said control switching means is actuated in response to the release of a clutch pedal, thereby disabling said motor.
Claim 7
Dependent Claim
43 words
The seat belt device according to claim 2 or 5, further including a second transmission shift lever switch actuated in response to the setting of the transmission shift lever to forward position for disabling the effect of the movement of the door switch.
Claim 8
Dependent Claim
28 words
The seat belt device according to claim 6, further including means responsive to the actuation of said second transmission shift lever switch for disabling said first changeover means.
Claim 9
Dependent Claim
119 words
The seat belt according device to claim 1, wherein said control switching means further includes an ignition switch, a pair of parallel connected transmission shift lever switches, one said shift lever switch being actuated when the transmission shift lever is in forward position and the other said shift lever being actuated when the transmission shift lever is in reverse position, and wherein said electric circuit first changeover means is responsive to said door switch and said front travel limit switch for driving said motor in the reverse direction, and wherein said electric circuit second transferring means is further responsive to said ignition switch and either of said transmission shift lever switches for driving said motor in the reverse direction.
Claim 10
Dependent Claim
42 words
The seat belt according device to claim 8, wherein said electric circuit further includes a normally closed switch opened when said ignition switch and either of said transmission shift lever switches are closed, thereby disabling the effect of said first transferring means.
Claim 11
Dependent Claim
93 words
The seat belt device according to claim 1, wherein said control switching means further includes an ignition switch, a hand brake switch, a first normally closed switch which is opened when said ignition switch and said hand brake switch are closed, and a second normally closed switch which is opened when said ignition switch is closed and said hand brake switch is open, whereby when said first normally closed switch is open, said second transferring means is disabled, and when said second normally closed switch is open, said first changeover means is disabled.
Claim 12
Dependent Claim
28 words
The seat belt device according to claim 1, 2, 3, 4, 5, 8, 9 or 10, wherein said slide mechanism is fixed to a door of said vehicle.
