Abstract

The disclosure discloses a seatbelt apparatus comprising a retractor device enabling one end side of a seatbelt, a belt anchor fixing the seatbelt, a support starting point member supporting one end side of the seatbelt, a tongue movably held by a part of the seatbelt, and a seatbelt buckle disposed opposite to the belt anchor beyond a seat cushion, the seatbelt apparatus being enabled to restrain a passenger by an engagement operation of the tang with the seatbelt buckle, the seatbelt apparatus further comprising a displacement member disposed on the support starting point member to be capable of displacing a start point position of the seatbelt to an initial position and to a moved position close to the shoulder of the passenger, and a drive device displacing the displacement member from the initial position to the moved position.

Claims

1. A seatbelt apparatus comprising:

a retractor device enabling one end side of a seatbelt to be wound and pulled out;

a belt anchor fixing the other end of the seatbelt;

a support starting point member supporting said one end side of said seatbelt;

a tongue movably held by a part of the seatbelt between said belt anchor and said support starting point member; and

a seatbelt buckle disposed opposite to said belt anchor beyond a seat cushion,

the seatbelt apparatus being enabled to restrain a passenger by an engagement operation of said tang with said seatbelt buckle while pulling out said seatbelt from the vicinity of said support starting point member,

the seatbelt apparatus further comprising

a displacement member disposed on said support starting point member to be capable of displacing a start point position of said seatbelt on the one end side to an initial position higher than a shoulder of the passenger and to a moved position close to the shoulder of the passenger, and

a drive device displacing said displacement member from the initial position to the moved position.

2. The seatbelt apparatus according to claim 1, further comprising an actuation device actuating said drive device when shock is applied to a vehicle body.

3. The seatbelt apparatus according to claim 1, wherein

said support starting point member includes:

a guide rail extending along a vertical direction of a vehicle body,

a slider as the displacement member, that is guided by said guide rail;

a tension member connected between said slider and said drive device, and

a shoulder anchor disposed on said slider to fold the one end side of said seatbelt.

4. The seatbelt apparatus according to claim 1, wherein

said guide rail has a positioning portion positioning said slider at the initial position and allowing said slider to be displaced to the moved position by a drive force of said drive device.

5. The seatbelt apparatus according to claim 1, wherein

said support starting point member is a shoulder anchor folding the one end side of the seatbelt, and

said drive device is an actuation member capable of being at least extended or contracted with said shoulder anchor fixed to one end of the actuation member.

6. The seatbelt apparatus according to claim 1, wherein

said support starting point member is a through anchor disposed on said retractor device, and

said drive device is an actuation member capable of being at least extended or contracted with said retractor device fixed to be displaceable at least either between an elevated position and a lowered position or between the outer side and the inner side of the vehicle body.
