[Claims]
[Claim 1]
Webbing to restrain occupants in vehicle seats,
A gas expansion type tension applying device that applies tension to the webbing with an expansion gas,
An electric tension applying device that winds up the webbing with an electric motor and applies tension to the webbing.
A control means for restraining the occupant by further tightening the webbing with the gas expansion type tension applying device after removing the slack of the webbing with the electric tension applying device.
Seat belt device with.
2.
The gas expansion type tension applying device is attached to a buckle portion on the side of the passenger compartment seat or a lap outer portion or a floor portion below the B pillar of the vehicle.
The electric tension applying device is attached to a retractor device under the B pillar of the vehicle.
The seatbelt device according to claim 1.
3.
The operation of the gas expansion type tension applying device is determined based on the impact at the time of a vehicle collision, and the operation is determined.
The operation of the electric tension applying device is determined based on the distance between the own vehicle and surrounding obstacles.
The seatbelt device according to claim 1.
4.
The control means
When it is predicted that a collision between the own vehicle and the obstacle is unavoidable, the electric tension applying device is activated.
After that, the gas expansion type tension applying device is operated based on the impact at the time of the vehicle collision.
The seatbelt device according to claim 3.
5.
The control means calculates the collision time required for the own vehicle and the obstacle to collide, and predicts that the collision is unavoidable when the collision time is equal to or less than a predetermined reference time.
The seatbelt device according to claim 4.
6.
The control means activates the gas expansion type tension applying device when the deceleration of the vehicle exceeds a reference value.
The seatbelt device according to claim 4.
7.
Webbing that restrains occupants in the seats of the vehicle,
With the pretensioner that pulls in the webbing,
A winding device that winds the webbing with a motor,
A collision detecting means for detecting the impact or collision of the vehicle, and
Danger prediction means for predicting a vehicle collision and
A control unit that controls the operation of the pretensioner and the take-up device based on at least the outputs of the collision detecting means and the danger predicting means.
With
The control unit operates the winding device based on the output of the danger predicting means, and then operates the pretensioner based on the output of the collision detecting means.
8.
The control unit changes the detection standard of the collision detecting means according to the presence or absence of operation of the winding device.
The seatbelt device according to claim 7.
9.
When the take-up device is operated based on the output of the danger predicting means, the control unit changes the operation reference of the pretensioner based on the output of the collision detecting means so as to be more difficult to operate.
