Claim 10

A webbing guide apparatus for use in a seatbelt system in which one end of a shoulder webbing is housed in a roof portion of the body of a vehicle, said apparatus comprising: (a) guide means for retaining an intermediate portion of the webbing, said guide means having one end thereof supported by a seat back rest or a head rest which is mounted on said seat back rest; (b) means for pivotally supporting said guide means on said seat back rest or said head rest; and (c) means for limiting the pivoting of said guide means about its pivotally supported portion, whereby, when said seat back rest is inclined toward the front of said vehicle, the intermediate portion of said webbing is caused to move forwardly and toward the roof of said vehicle in response to the forwardly inclining movement of said seat back rest, thereby providing a space so that an occupant can smoothly enter or leave a back seat of said vehicle.

Claim 11

A webbing guide apparatus for use in a seatbelt system in which one end of a shoulder webbing is housed in a roof portion of the body of a vehicle, said apparatus comprising: (a) guide means for retaining an intermediate portion of the webbing, said guide means having one end thereof supported by a seat back rest or a head rest which is mounted on said seat back rest; (b) means for pivotally supporting said guide means on said seat back rest or said head rest; and (c) means for limiting the pivoting of said guide means about its pivotally supported portion, whereby, when said seat back rest is inclined toward the front of said vehicle, the intermediate portion of said webbing is caused to move forwardly and toward the roof of said vehicle in response to the forwardly inclining movement of said seat back rest, thereby providing a space so that an occupant can smoothly enter or leave a back seat of said vehicle.

Claim 12

A webbing guide apparatus according to claim 9, wherein said guide means has a tube shape which allows said webbing to pass through the inside thereof.

Claim 13

A webbing guide apparatus according to claim 9, wherein said guide means is twisted at its longitudinally central portion about its longitudinal axis so as to smoothly guide a twisted portion of said webbing which extends between said roof portion and an occupant fastening portion of said webbing.

Claim 14

A webbing guide apparatus according to claim 9, wherein said limiting means comprises at least one abuting member which is provided on said head rest and adapted to contact said guide means when said guide means is pivoted, whereby, when said seat back rest is forwardly inclined, the pivoting angle of said guide means is limited, and the intermediate portion of said webbing is thereby moved forward and toward the roof of said vehicle in response to the forwardly inclining movement of said seat back rest.

Claim 15

A webbing guide apparatus according to claim 12, wherein said limiting means comprises by a pin which projects from said head rest and abuts against said guide means.

Claim 16

A webbing guide apparatus according to claim 9, wherein said guide means comprises by a rod member which has one end thereof pivotally supported by said seat back rest and has a webbing guide portion formed at its distal end.

Claim 17

A webbing guide apparatus according to claim 14, wherein said webbing guide portion is formed by bending the distal end portion of said rod member into a substantially U-shape, said guide portion being employed to receive the intermediate portion of said webbing.

Claim 18

A webbing apparatus employed in a seatbelt system in which a tongue plate is retained on an intermediate portion of a continuous webbing which has one end thereof secured to a lower portion of the body of a vehicle and the other end secured to a roof portion of the vehicle body, said apparatus comprising: (a) guide means pivotally supported by a head rest which is mounted on a seat back rest, said guide means being adapted to allow the intermediate portion of said webbing to pass through the inside thereof, and said guide means having a distal end projecting from said head rest; and (b) means for limiting the range of pivoting of said guide means, said limiting means being provided between said head rest and said guide means, whereby, when said seat back rest is inclined toward the front of said vehicle, the intermediate portion of said webbing is bent in such a manner as to move forwardly and toward the roof portion of said vehicle, thereby providing a space which is required for an occupant to smoothly enter or leave a back seat of said vehicle.

Claim 19

A webbing apparatus employed in a seatbelt system in which a tongue plate is retained on an intermediate portion of a continuous webbing which has one end thereof secured to a lower portion of the body of a vehicle and the other end secured to a roof portion of the vehicle body, said apparatus comprising: (a) guide means pivotally supported by a head rest which is mounted on a seat back rest, said guide means being adapted to allow the intermediate portion of said webbing to pass through the inside thereof, and said guide means having a distal end projecting from said head rest; and (b) means for limiting the range of pivoting of said guide means, said limiting means being provided between said head rest and said guide means, whereby, when said seat back rest is inclined toward the front of said vehicle, the intermediate portion of said webbing is bent in such a manner as to move forwardly and toward the roof portion of said vehicle, thereby providing a space which is required for an occupant to smoothly enter or leave a back seat of said vehicle.
