Automatic seat belt system

An automatic seat belt system comprising:

• a guide rail mounted on a region extending from a front pillar to a center pillar of a vehicle body;
• a slider to which one end of a webbing for restraining an occupant is supported, said slider having slider members, said slider being movable longitudinally along guide rail via said slider members and disposed in a manner so as to be swingably movable with respect to said guide rail and said slider members;
• a driving tape on which said slider is mounted, said tape being movable reciprocatively along said guide rail;
• driving means for moving said tape along the longitudinal direction of said guide rail so as to dispose said slider in either one of two positions where said webbing restrains an occupant or releases the occupant therefrom;
• and
• a stopper engaged with said slider in the webbing-restraining position so as to prevent said slider from being moved in the direction to which the webbing is pulled, said stopper being brought into engagement with said slider when a load is applied in an upward direction to said slider so that said slider is swingingly moved upward, thereby preventing said slider from being moved upward along said guide rail.

An automatic seat belt system comprising:

• a guide rail mounted on a vehicle body;
• a slider to which one end of a webbing for restraining an occupant is supported, said slider being movable longitudinally along guide rail via and disposed in a manner so as to be swingable with respect to said guide rail;
• an elongated member on which said slider is mounted, said elongated member being movable reciprocatively along the length of said guide rail;
• driving means for moving said elongated member longitudinally along the guide rail so as to dispose said slider in either one of two positions where said webbing restrains an occupant and releases the occupant therefrom;
• and
• a stopper engaged with said slider in the webbing-restraining position so as to prevent said slider from being moved in the direction to which the webbing is pulled, said stopper being brought into engagement with said slider when a load is applied in an upward direction to said slider so that said slider is swingingly moved upward, thereby preventing said slider from being moved upward along said guide rail wherein said slide includes a pair of slider members capable of sliding along said guide rail, wherein said slider is swingable with respect to said slider members and wherein said slider members include urging means for urging said slider in such a direction as to prevent said slider being swingably moved.

An automatic seat belt system comprising:

• a guide rail mounted on a region extending from a front pillar to a center pillar of a vehicle body;
• a slider made of a plate member to which one end of a webbing for restraining an occupant is supported;
• slider members disposed on both side faces of said slider, said slider members supporting said slider thereon wherein said slider members are movable along said guide rail and wherein said slider is swingable with respect to said slider members;
• a driving tape on which said slider is mounted, said tape being movable reciprocatively along said guide rail;
• driving means for moving said tape longitudinally along said guide rail so as to dispose said slider in either one of two positions where said webbing restrains the occupant or releases the occupant therefrom;
• a stopper engaged with said slider in the webbing-restraining position so as to prevent said slider from being moved in a direction to which the webbing is pulled, said stopper being brought into engagement with said slider when said slider is subjected to a load, thereby preventing said slider from being moved along said guide rail;
• and
• a stopper holding member for holding said stopper in position.
