  • Patent number: 12459411
    Abstract: Described is a vehicular seat having a back element. The back element includes: (a) a rigid support element having coupled thereto an anchor element, the anchor element for detachably coupling to an article; and (b) a resilient foam element secured with respect to the rigid support element. The resilient foam element is in contact with the back of an occupant of the vehicular seat. The article can be one or more of an occupant restraint element, a cargo element and an automotive accessory. Advantageously, this combination of elements results in a vehicular seat, which is of light weight construction and passes the FMVSS 225 test requirement.
