Abstract: A vehicle includes a vehicle frame including a first frame rail, a second frame rail spaced cross-vehicle from the first frame rail, and a middle frame rail between the first frame rail and the second frame rail. The first frame rail and the second frame rail each have a vehicle-inboard side facing toward the middle frame rail. The vehicle-inboard sides each define a plurality of notches. The middle frame rail has a downward side facing downwardly and perpendicular to the vehicle-inboard sides. The downward side defining a plurality of notches. The vehicle frame has a rear cross-member and a front cross-member spaced vehicle-forward of the rear cross-member. The rear cross-member and the front cross-member are between the first frame rail and the second frame rail. The notches of the vehicle-inboard sides and the notches of the downward side are between the rear cross-member and the front cross-member.

Abstract: A wheel assembly includes a rim, an inner hub concentric with the rim, and an outer hub concentric with the rim and the inner hub. The outer hub is between the rim and the inner hub. The wheel assembly includes a first set of spokes spaced circumferentially about the inner hub between the inner hub and the outer hub. The first set of spokes are elongated radially from the inner hub and having a sinusoidal shape. The wheel assembly includes a second set of spokes spaced circumferentially about the outer hub between the outer hub and the rim. The second set of spokes are elongated radially from the outer hub and having a sinusoidal shape. The second set of spokes are aligned with the first set of spokes circumferentially about the outer hub.

Abstract: A vehicle includes a frame including a first post, a second post spaced cross-vehicle from the first post, and a steering post rotatably supported by the frame. The steering post extends between the first and second posts. The vehicle includes a steering post reinforcement having a first and a second end each fixed to the frame, a curved portion curving about the axis between the ends, and a first and a second portion extending from the ends to the curved portion. The first and second portions are elongated vehicle-rearward from the frame to the curved portion. The curved portion defines an opening between the ends. The steering post extends through the opening between the curved portion and the frame and between the first and second portions. The curved portion is spaced vehicle-rearward from the steering post. The first and second portions are spaced cross-vehicle from the steering post.

Abstract: A vehicle includes a pair of frame rails and a bumper assembly. The bumper assembly includes a bumper beam supported by the frame rails and an airbag. The airbag includes a first airbag chamber supported by the bumper beam and inflatable to an inflated position, and a second airbag chamber supported by the bumper and inflatable to an inflated position. The first airbag chamber is disposed in a cross-vehicle direction relative to the second airbag chamber. The first airbag chamber has a first volume in the inflated position. The second airbag chamber has a second volume in the inflated position. The first volume is different than the second volume.

Abstract: A network of rails for a vehicle includes a lateral rail that extends primarily along a lateral axis of the vehicle, a longitudinal rail that extends primarily along a longitudinal axis of the vehicle, and a circular rail that interacts with at least one of the lateral rail and the longitudinal rail.

Abstract: A vehicle frame assembly includes, among other things, a lower main rail of a vehicle, a deflector assembly that is disposed adjacent a forward end portion of the lower main rail, and a positioning bracket of the deflector assembly. The positioning bracket is secured directly to the lower main rail and configured to separate from the lower main rail if a load that exceeds a threshold load is applied to a front of the vehicle.

Abstract: A system includes a sensor, a controller, and a seatbelt retractor. The controller is programmed to receive a signal from the sensor indicating detection of a vehicle front oblique impact. The seatbelt retractor includes a load limiting mechanism selectively releasable from a high load mode to a low load mode. The controller is programmed to release the load limiting mechanism from the high load mode to the low load mode at a predetermined time in response to a signal from the sensor indicating a vehicle front oblique impact.
