Abstract
Abstract An element fixedly mounted in a motor vehicle having a free end and an aperture spaced apart therefrom is provided for securing an inner end portion of a flexible tether to the vehicle for restraining an air bag cover during air bag deployment. An attachment connector having a hook at one end is adapted to be engaged in hooked relation over the free end of the fixed element with the inner end portion of the tether sandwiched between facing adjacent surfaces of the attachment connector and the fixed element. A unidirectional, self-locking, snap-in-type, fastener mounted on the attachment connector remote from the hook end has a shank that is passed through the tether and is thereafter positioned to extend through the aperture of the fixed element when the attachment connector is engaged with the fixed element and pivoted about the hook end with the tether in sandwiched relation between the fixed element and the attachment connector. After the hook end is in place, the attachment connector is moved toward the fixed element until the fastener passes through the aperture and snaps into place for positively locking the tether, fixed element and attachment connector positively together without requiring the use of tools or other implements.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
173 words
Apparatus for positively connecting an end portion of an air bag door tether formed of flexible material to a motor vehicle, comprising: a fixed element fixedly mounted in a motor vehicle formed with a free end and a fastener receiving aperture spaced apart from said free end; an attachment bracket having a hook at one end adapted to be hooked over the free end of said fixed element; a tether formed of flexible material for restraining movement of an air bag door during air bag deployment having an end portion sandwiched between facing surfaces of said bracket and the fixed element; and a fastener on said bracket remote from said hook having a shank with compressible holding means thereon positioned to be compressed when passed through the aperture from one side of the fixed element and expandable after passage to engage an opposite side of the fixed element for retaining said hook in position hooked over the free end with said tether sandwiched between facing surfaces of said bracket and the fixed element.
Claim 2
Dependent Claim
173 words
Apparatus for positively connecting an end portion of an air bag door tether formed of flexible material to a motor vehicle, comprising: a fixed element fixedly mounted in a motor vehicle formed with a free end and a fastener receiving aperture spaced apart from said free end; an attachment bracket having a hook at one end adapted to be hooked over the free end of said fixed element; a tether formed of flexible material for restraining movement of an air bag door during air bag deployment having an end portion sandwiched between facing surfaces of said bracket and the fixed element; and a fastener on said bracket remote from said hook having a shank with compressible holding means thereon positioned to be compressed when passed through the aperture from one side of the fixed element and expandable after passage to engage an opposite side of the fixed element for retaining said hook in position hooked over the free end with said tether sandwiched between facing surfaces of said bracket and the fixed element.
