A body structure for an automotive vehicle includes an enclosure for a power source, an upper shear structure assembly and a lower shear structure assembly. The enclosure includes a front cross-member, a rear cross-member, a left rocker and a right rocker. The upper and lower shear structure assemblies are disposed across the top and bottom of the enclosure, respectively, and are fastened to respective top and bottom surfaces of the cross-members and rockers. The upper and lower shear structure assemblies may include respective front and rear generally trapezoidal sections configured for attachment to respective front and rear box structures. Each of the shear structure assemblies is effective to dissipate in-plane a portion of an external load imposed upon the enclosure.

A barrier assembly for an energy storage system includes a panel and an energy storage pack. The panel includes an outer surface and an inner surface opposing the outer surface. The energy storage pack is spaced from the panel relative to the inner surface of the panel. The barrier assembly further includes an intermediate structure disposed between the inner surface of the panel and the energy storage pack. The intermediate structure is configured to absorb energy when a load is applied to the outer surface of the panel and configured to redistribute the load along a plurality of load paths through the intermediate structure as the load is applied to the panel. A vehicle includes the barrier assembly discussed above. The vehicle includes a support structure and the barrier assembly is coupled to the support structure. The inner surface of the panel faces toward the support structure.

A structural arrangement for a vehicle includes a body structure defining a longitudinal vehicle body axis and a lateral vehicle axis orthogonal to the longitudinal vehicle body axis. The body structure includes a lattice shear structure having a first structural member extending laterally from one side to an opposite side of the vehicle and a second structural member parallel to and longitudinally spaced apart from the first structural member, an upper shear panel extending longitudinally and laterally across the vehicle and joined to the lattice shear structure, and a seat attachment structure having a first end and a second end opposite the second end. The seat attachment structure is oriented longitudinally and is joined to both of the first and second structural members.

Vehicle seat structure flexibility within shear integral structures

A panel assembly is formed by a plurality of bonds between two sheet materials in a face to face relationship to form a preform. The plurality of bonds define a closed perimeter region between the two sheet materials and an open perimeter region between the two sheet materials. The preform may be formed into a predefined shape. Pressurized fluid is applied through an inlet into the open perimeter region to expand the preform. The pressurized fluid expands the open perimeter region such that the two sheet materials expand in an opposing direction, thereby defining an expanded open perimeter region. The closed perimeter region between the two sheet materials remains vacant of the pressurized fluid such that the closed perimeter region is not expanded. The expanded open perimeter region is filled with a filler material for improving a performance characteristic of the panel assembly, e.g., strength, sound absorption, or stiffness.
