  • Patent number: 11072412
    Abstract: A mounting member for a vehicle, the mounting member including a mounting member body having a longitudinal axis, at least one static opening extending through the body transverse to the longitudinal axis, and at least one blind listener bushing, each blind fastener bushing having a bushing body and a blind fastener receptacle extending axially through the bushing body. The bushing body has a bushing cross-sectional shape that interlocks and couples with a static opening cross-sectional shape of a respective one of the at least one static opening so that rotation of the at least one blind fastener bushing is constrained relative to the mounting member body and the static opening cross-sectional shape is maintained upon application of a blind fastener installation torque or blind fastener removal torque being applied to the blind fastener receptacle by a respective blind fastener.

  • Patent number: 9815544
    Abstract: Systems, methods, and apparatus for a modular replaceable slip joint intercostal are disclosed. In one or more embodiments, an intercostal apparatus for a vehicle comprises a body, where the body is greater in length than in width. In at least one embodiment, the intercostal apparatus further comprises at least one slip joint opening located proximate an end of the body to slidably receive a bushing and a fastener, where the bushing rigidly attaches to a top surface of a seat track by the fastener.
