Abstract: A device for detachably securing an object on a motor vehicle seat includes a transverse support member mountable adjacent to and along a gap between a seating surface and backrest of the motor vehicle seat and a pair of securements spaced apart and mounted to the support member so as to extend into the gap and being adapted for securing the object on the seating surface. Each securement includes a set of elements and structures connecting at least some of the elements of each set with one another and with the support member such that the securements are swivellable in planes defined by the securements relative to the support member between extended positions of use and retracted positions of rest. In positions of use, the securements have U-shaped configurations formed by the sets of elements such that one securement is identical to and a mirror image of the other securement.
