Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
193 words
In a vehicle safety seatbelt system, the combination comprising: a support a reel rotatably mounted on the support; a belt connected to the reel so as to be extended as the reel is rotated in an unwinding direction, and to be retracted as the reel is rotated in the opposite, winding direction; an actuator mounted on the reel to respond to certain accelerated reel motions in the unwinding direction; a locking member movably mounted on the support for motion between a locking position to prevent reel rotation in the unwinding direction and a second position to allow reel rotation; bias means mounted on the support for urging the locking member toward said first and second positions; and dog means pivotably disposed in an opening in the actuator for connecting the locking member to the actuator, said dog means cooperating with an intermediary member having mounted thereon pin-in-slot means connected to said locking member for automatically moving the locking member to its locking position in response to the reel being rotated with said accelerated motions, and automatically moving the locking member to its release position in response to reel rotation in the winding direction.
Claim 2
Dependent Claim
193 words
In a vehicle safety seatbelt system, the combination comprising: a support a reel rotatably mounted on the support; a belt connected to the reel so as to be extended as the reel is rotated in an unwinding direction, and to be retracted as the reel is rotated in the opposite, winding direction; an actuator mounted on the reel to respond to certain accelerated reel motions in the unwinding direction; a locking member movably mounted on the support for motion between a locking position to prevent reel rotation in the unwinding direction and a second position to allow reel rotation; bias means mounted on the support for urging the locking member toward said first and second positions; and dog means pivotably disposed in an opening in the actuator for connecting the locking member to the actuator, said dog means cooperating with an intermediary member having mounted thereon pin-in-slot means connected to said locking member for automatically moving the locking member to its locking position in response to the reel being rotated with said accelerated motions, and automatically moving the locking member to its release position in response to reel rotation in the winding direction.
Claim 3
Dependent Claim
37 words
The combination as defined in claim 1, in which said actuator includes an inertia member mounted on the reel so as to be movable thereon in accordance with certain rotational accelerations of the reel on the support.
Claim 4
Dependent Claim
22 words
The combination as defined in claim 2, including means for controlling the rotational displacement of the actuator with respect to the reel.
Claim 5
Dependent Claim
36 words
The combination as defined in claim 1, in which the actuator is movable with respect to the locking member at such times as the locking member is disposed to prevent reel rotation in the unwinding direction.
