Automatic seatbelt system

Claim 2

An automatic seatbelt system for automatically fastening and unfastening a seatbelt in a vehicle, comprising: a seatbelt including an end; an anchor plate connected to said end of the seatbelt; a guide means being fixed to a vehicle body, the guide means having a longitudinally extending groove therein in which the anchor plate is slidably mounted; a transmitting means for transmitting a driving force to the anchor plate, said transmitting means including a plurality of balls which have openings therein, a wire which extends through the openings of the balls, and a biasing means, said biasing means functioning to force adjacent balls of the plurality of balls toward each other, said biasing means being fixed to said wire; and a driving means for generating said driving force to move the transmitting means, thereby moving the anchor plate; whereby when a vehicle door opens, the driving means generates the driving force which is transmitted by the transmitting means to the anchor plate, thereby forwardly moving the seatbelt in the vehicle to enable a passenger to get in or out and whereby when the vehicle door closes, the driving means generates the driving force which is transmitted by the transmitting means to the anchor plate, thereby rearwardly moving the seatbelt in the vehicle to enable the passenger to fasten the seatbelt.

Claim 3

The automatic seatbelt system of claim 1, further comprising a flexible tube, said biasing means being located within said flexible tube, said flexible tube being fixed to said housing.

Claim 4

The automatic seatbelt system of claim 1, wherein the anchor plate includes a sliding portion, said wire being fixed to said sliding portion.

Claim 5

The automatic seatbelt system of claim 3, wherein the driving means includes a sprocket wheel which is fixed to a center pillar of the vehicle body and which is rotated by the driving means, the sprocket wheel including a peripheral portion which engages with the transmitting means.

Claim 6

The automatic seatbelt system of claim 4, further comprising a housing having L-shaped passages, said housing surrounding said sprocket wheel, said L-shaped passages functioning to guide said transmitting means.

Claim 7

The automatic seatbelt system of claim 3, wherein said wire includes an intermediate portion, a first end and a second end, said sliding portion being fixed to said first end of said wire.

Claim 8

The automatic seatbelt system of claim 6, wherein said second end of said wire is fixed to said biasing means.

Claim 9

The automatic seatbelt system of claim 7, wherein said plurality of balls fill said intermediate portion of said wire.

Claim 10

A seatbelt system for automatically fastening and unfastening a seatbelt in a vehicle, comprising: a seatbelt including an end; an anchor plate connected to said end of said seatbelt; a guide means being fixed to a vehicle body, the guide means having a longitudinally extending groove therein in which the anchor plate is slidably mounted; a transmitting means for transmitting a drive force to the anchor plate, said transmitting means including a plurality of balls which have openings therein, a wire which extends through the openings of said balls, and a biasing means, said wire including a first end, a second end and an intermediate portion, said balls covering said intermediate portion of said wire, said biasing means functioning to force adjacent balls of the plurality of balls toward each other, said biasing means being fixed to said wire; and a driving means for generating the driving force to move the transmitting means thereby moving the anchor plate; whereby when a vehicle door opens, the driving means generates the driving force which is transmitted by the transmitting means to the anchor plate thereby outwardly moving the seatbelt in the vehicle to enable the passenger to get in or out and whereby when the vehicle door closes, the driving means generates the driving force which is transmitted by the transmitting means to the anchor plate, thereby rearwardly moving the seatbelt in the vehicle to enable the passenger to fasten the seatbelt.

Claim 11

A seatbelt system for automatically fastening and unfastening a seatbelt in a vehicle, comprising: a seatbelt including an end; an anchor plate connected to said end of said seatbelt; a guide means being fixed to a vehicle body, the guide means having a longitudinally extending groove therein in which the anchor plate is slidably mounted; a transmitting means for transmitting a drive force to the anchor plate, said transmitting means including a plurality of balls which have openings therein, a wire which extends through the openings of said balls, and a biasing means, said wire including a first end, a second end and an intermediate portion, said balls covering said intermediate portion of said wire, said biasing means functioning to force adjacent balls of the plurality of balls toward each other, said biasing means being fixed to said wire; and a driving means for generating the driving force to move the transmitting means thereby moving the anchor plate; whereby when a vehicle door opens, the driving means generates the driving force which is transmitted by the transmitting means to the anchor plate thereby outwardly moving the seatbelt in the vehicle to enable the passenger to get in or out and whereby when the vehicle door closes, the driving means generates the driving force which is transmitted by the transmitting means to the anchor plate, thereby rearwardly moving the seatbelt in the vehicle to enable the passenger to fasten the seatbelt.
