Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 246 words
A seat belt apparatus for a transportation device, the transportation device having a door with a handle, a locking device and a linking rod operatively linking the handle with the locking device, comprising: a tongue secureable on one end of a seat belt; buckle means engageable with the tongue; means for releasing the tongue from engagement with the buckle means in response to opening of the door, the releasing means comprising a sliding member engageable at one end with the linking rod and at another end with the buckle means, the sliding member being adapted to slide in association with movement of the linking rod during opening of the door, whereby the sliding member operates the buckle means to release the tongue; and means for preventing the releasing means from releasing the tongue from engagement with the buckle means when the transportation device accelerates or decelerates, comprising: a pawl adapted to pivot, in response to acceleration or deceleration of the transportation device, about an axis which is transverse to the direction of movement of the transportation device, an actuator for interconnecting the pawl and the sliding member, the actuator having one end biased in contact with the pawl and being adapted to move the sliding member out of engagement with the linking rod when the pawl pivots in response to acceleration or deceleration, whereby the sliding member does not slide in association with movement of the linking rod during acceleration or deceleration of the transportation device.
Claim 2
Dependent Claim 246 words
A seat belt apparatus for a transportation device, the transportation device having a door with a handle, a locking device and a linking rod operatively linking the handle with the locking device, comprising: a tongue secureable on one end of a seat belt; buckle means engageable with the tongue; means for releasing the tongue from engagement with the buckle means in response to opening of the door, the releasing means comprising a sliding member engageable at one end with the linking rod and at another end with the buckle means, the sliding member being adapted to slide in association with movement of the linking rod during opening of the door, whereby the sliding member operates the buckle means to release the tongue; and means for preventing the releasing means from releasing the tongue from engagement with the buckle means when the transportation device accelerates or decelerates, comprising: a pawl adapted to pivot, in response to acceleration or deceleration of the transportation device, about an axis which is transverse to the direction of movement of the transportation device, an actuator for interconnecting the pawl and the sliding member, the actuator having one end biased in contact with the pawl and being adapted to move the sliding member out of engagement with the linking rod when the pawl pivots in response to acceleration or deceleration, whereby the sliding member does not slide in association with movement of the linking rod during acceleration or deceleration of the transportation device.
