Abstract
Abstract An improved three-point passive belt restraint system having a flexible shoulder belt positioning arm. The flexible belt positioning arm is adapted for positioning the shoulder belt adjacent the occupants shoulder when the belt restraint system is in the occupant restraint position. Further, the flexible belt positioning arm is mounted to a sled whereby the sled and positioning arm are moved away from the occupant to an occupant non-restraint position upon door opening. The flexible belt positioning arm includes an upper tube arm attached to the sled and a lower tube arm which includes a web guide for guiding and positioning the shoulder belt adjacent the occupant's shoulder. The upper and lower tube arms are connected at their inner ends by a flexible connection. The flexible connection allows flexing of the upper and lower tube arms relative each other to prevent occupant injury during crash conditions or inadvertent contact.

Total Claims: 15
Claim 1
Independent Claim
161 words
A flexible belt positioning arm adapted for use in a three point passive belt restraint system having two lower seat belt segments and an upper shoulder belt segment, the belt segments being movable between occupant restraint and non-restraint positions, the flexible belt positioning arm being adapted for positioning said upper shoulder belt segment about an occupant in a vehicle, the flexible belt positioning arm comprising: a flexible tube arm wherein said tube arm includes an upper tube arm and a lower tube arm and a flexible connection means for flexibly connecting said upper tube arm to said lower tube arm; a lower web guide or positioner associated with said tube arm for guiding and positioning said shoulder belt segment passed therethrough; and means for mounting said flexible tube arm to said vehicle to place said lower web guide where it will position said shoulder belt segment adjacent the vehicle passengers shoulder when said restraint system is in the passenger restraint position.
Claim 2
Dependent Claim
161 words
A flexible belt positioning arm adapted for use in a three point passive belt restraint system having two lower seat belt segments and an upper shoulder belt segment, the belt segments being movable between occupant restraint and non-restraint positions, the flexible belt positioning arm being adapted for positioning said upper shoulder belt segment about an occupant in a vehicle, the flexible belt positioning arm comprising: a flexible tube arm wherein said tube arm includes an upper tube arm and a lower tube arm and a flexible connection means for flexibly connecting said upper tube arm to said lower tube arm; a lower web guide or positioner associated with said tube arm for guiding and positioning said shoulder belt segment passed therethrough; and means for mounting said flexible tube arm to said vehicle to place said lower web guide where it will position said shoulder belt segment adjacent the vehicle passengers shoulder when said restraint system is in the passenger restraint position.
