Claim 1
Independent Claim
329 words
A safety seatbelt assembly for a vehicle having a seat comprising a seat cushion portion and a backrest portion which is mounted on a rear portion of said seat cushion portion, said safety seatbelt assembly comprising: (a) a flexible seatbelt having one end thereof firmly connected to one side of said seat cushion portion and the other end thereof equipped with first fastening means, said seatbelt being capable of crossing said seat to restrain a vehicle passenger sitting thereon; (b) an elongated shaft secured at its one end to the other side of said seat cushion portion at a location adjacent said rear portion of said seat cushion portion and formed at its leading end with a ball-shaped head portion; (c) an elongated rigid member having a lower portion which is formed with a flanged opening into which said ball-shaped head portion is rotatably received, said elongated rigid member having at its upper end a second fastening means which is engagable with said first fastening means to permit said seatbelt to restrain a vehicle passenger; (d) a cover plate having a hemispherical recess formed therein which faces said flanged opening, said cover plate being secured to said elongated rigid member such that said elongated rigid member is universally rotatably supported on said ball-shaped head portion by said flanged opening and said hemispherical recess; (e) a coil spring disposed about said elongated shaft having one end thereof engaging said seat cushion portion and the other end thereof engaging said elongate rigid member so as to simultaneously bias said elongate rigid member to rotate about said ball-shaped head portion toward a dormant position in which a longitudinal axis of the elongate rigid member is substantially parallel to a plane defined by a front surface of said backrest portion, and in a direction away from said seat cushion portion; and (f) a stop member mounted on said seat cushion portion which engages said elongate rigid member to prevent the excessive rotation thereof.

A safety seatbelt assembly for a vehicle having a seat comprising a seat cushion portion and a backrest portion which is mounted on a rear portion of said seat cushion portion, said safety seatbelt assembly comprising: (a) a flexible seatbelt having one end thereof firmly connected to one side of said seat cushion portion and the other end thereof equipped with first fastening means, said seatbelt being capable of crossing said seat to restrain a vehicle passenger sitting thereon; (b) an elongated shaft secured at its one end to the other side of said seat cushion portion at a location adjacent said rear portion of said seat cushion portion and formed at its leading end with a ball-shaped head portion; (c) an elongated rigid member having a lower portion which is formed with a flanged opening into which said ball-shaped head portion is rotatably received, said elongated rigid member having at its upper end a second fastening means which is engagable with said first fastening means to permit said seatbelt to restrain a vehicle passenger; (d) a cover plate having a hemispherical recess formed therein which faces said flanged opening, said cover plate being secured to said elongated rigid member such that said elongated rigid member is universally rotatably supported on said ball-shaped head portion by said flanged opening and said hemispherical recess; (e) a coil spring disposed about said elongated shaft having one end thereof engaging said seat cushion portion and the other end thereof engaging said elongate rigid member so as to simultaneously bias said elongate rigid member to rotate about said ball-shaped head portion toward a dormant position in which a longitudinal axis of the elongate rigid member is substantially parallel to a plane defined by a front surface of said backrest portion, and in a direction away from said seat cushion portion; and (f) a stop member mounted on said seat cushion portion which engages said elongate rigid member to prevent the excessive rotation thereof.
Claim 3
Dependent Claim
323 words
A safety seat belt assembly for a seat which includes a seat cushion portion and a backrest portion mounted on said seat cushion portion, said safety seat belt assembly comprising: (a) a flexible seat belt having one end thereof mounted on one side of said seat and the other end thereof equipped with a first fastening member, said seat belt being capable of crossing said seat to restrain a passenger sitting thereon; (b) an elongated rigid member positioned on the other side of said seat, having at its upper end a second fastening member which is engageable with said first fastening member for restraining a passenger in said seat; (c) an elongated shaft having one end secured to a lateral side of said seat cushion portion on the side opposite to which said flexible seat belt is attached, and the other end having a ball-shaped head portion; (d) a socket portion comprising a hemispherically flanged hole integrally formed on a lower end of said elongated rigid member into which said ball-shaped head of said elongated shaft is rotatably received, and a cover plate having a hemispherical recess formed therein which faces said flanged hole, said cover plate being secured to said elongated rigid member such that said elongated rigid member is universally rotatably supported on said ball-shaped head by said flanged hole and hemispherical recess, and is rotatable from a dormant position, in which a longitudinal axis of said elongated rigid member is substantially parallel to a plane defined by the front surface of said seat backrest portion and is rotated in a direction away from said seat cushion portion, to a forward position; and, (e) a coil spring disposed about said elongated shaft with one end thereof engaging said lateral side of said seat cushion portion, and the other end thereof engaging said elongated rigid member at its lower end so that said elongated rigid member is biased in said dormant position.
Claim 4
Dependent Claim
323 words
A safety seat belt assembly for a seat which includes a seat cushion portion and a backrest portion mounted on said seat cushion portion, said safety seat belt assembly comprising: (a) a flexible seat belt having one end thereof mounted on one side of said seat and the other end thereof equipped with a first fastening member, said seat belt being capable of crossing said seat to restrain a passenger sitting thereon; (b) an elongated rigid member positioned on the other side of said seat, having at its upper end a second fastening member which is engageable with said first fastening member for restraining a passenger in said seat; (c) an elongated shaft having one end secured to a lateral side of said seat cushion portion on the side opposite to which said flexible seat belt is attached, and the other end having a ball-shaped head portion; (d) a socket portion comprising a hemispherically flanged hole integrally formed on a lower end of said elongated rigid member into which said ball-shaped head of said elongated shaft is rotatably received, and a cover plate having a hemispherical recess formed therein which faces said flanged hole, said cover plate being secured to said elongated rigid member such that said elongated rigid member is universally rotatably supported on said ball-shaped head by said flanged hole and hemispherical recess, and is rotatable from a dormant position, in which a longitudinal axis of said elongated rigid member is substantially parallel to a plane defined by the front surface of said seat backrest portion and is rotated in a direction away from said seat cushion portion, to a forward position; and, (e) a coil spring disposed about said elongated shaft with one end thereof engaging said lateral side of said seat cushion portion, and the other end thereof engaging said elongated rigid member at its lower end so that said elongated rigid member is biased in said dormant position.
