The granted patent (Publication Number: US11964696B2) discloses a structural frame for a motor vehicle body that includes a pair of pillars joined to a roof crossmember and a structural cross-brace. The structural cross-brace supports vehicle suspension connectors and is designed to provide an unobstructed space in the occupant compartment between the pillars. The cross-brace comprises a cross-member and arms that secure it to the pillars, forming a U-shape in plan. Additionally, frame struts connect the cross-brace to the roof crossmember, ensuring structural integrity.

Furthermore, the structural frame includes features such as a base for mounting the pillars, an arcuate design for the cross-brace, and stiffening flanges for added support. The cross-brace can define the front or rear end of the occupant compartment and is shaped to correspond with a glazing member, securing the glazing member and defining the periphery of the compartment. The patent also covers a vehicle body incorporating this structural frame, where the cross-brace conforms to the vehicle's front profile and may serve as an exterior surface. Additionally, a vehicle with a chassis assembly to which the structural frame is mounted is described, with the option for detachable securing of the frame or body to the chassis assembly.
