  • Patent number: 10526015
    Abstract: A push arm is coupled to a vehicle frame proximate an intersection of a first side member and a first cross-member. A rear surface of the push arm is located adjacent to a front suspension structure with a gap defined therebetween. The push arm extends forward and laterally outward such that a front surface of the push arm is located outboard of and spaced apart from a front end of the first side member. An energy absorbing structure is positioned within the gap and is attached to the rear surface of the push arm and is spaced apart from the front suspension structure in a non-impacted state. The energy absorbing structure is configured such that in response to an off-center impact event, impact force to the energy absorbing structure pushes the energy absorbing structure into contact with the front suspension structure.

  • Patent number: 10464610
    Abstract: A vehicle structure includes a vehicle frame, a beam, an attachment bracket. The vehicle frame has a first side member, a second side member and a cross-member rigidly fixed to each of the first and second side members and extending between the first and second side members. The beam extends rearward from a mid-portion of the cross-member with a gap being defined between the beam and the cross-member. The attachment bracket is rigidly fixed to the mid-portion of the cross-member and retaining the beam. The attachment bracket is configured to maintain the gap with the vehicle frame in a non-impacted state. The attachment bracket is further configured such that in response an impact event impacting a forward area of the vehicle frame, with impacting forces causing relative movement between the cross-member and the attachment bracket, the gap is diminished or closed.

  • Patent number: 10377420
    Abstract: An off-center impact reinforcement structure includes a push arm proximate rearward of a front portion of the vehicle frame. The push arm extends in a forward and laterally outboard direction from a front side member. A rear surface of the push arm is located below the first side member. During an initial stage of an off-center impact event in which a stationary barrier directly impacts a front surface of the push arm, impacting forces from the off-center impact event move the rear surface of the push arm into contact with brackets that extend downward from the front side member and transfer through the push arm to brackets and to the vehicle frame. In a second stage, a rear surface of the push arm contacts the vehicle frame as the push arm pivots with the front surface of the push arm moving in a laterally outboard direction.

  • Patent number: 10150509
    Abstract: A vehicle structure includes a frame and a diagonal structure. The frame has a first side member, a second side member and a cross-member that extends in a vehicle lateral direction between the first and second side members. The cross-member is perpendicular to the first and second side members. The diagonal structure has a beam with a rear end that extends to an area of the second side member rearward of the cross-member. An angle of between 35 and 60 degrees is defined between the cross-member and the beam of the diagonal structure. The rear end of the beam is supported to the second side member by a rear attachment bracket such that the rear end of the beam is spaced apart from the second side member with a rear gap being defined between the rear end of the beam and the second side member.

  • Patent number: 10029732
    Abstract: A first structure extends to a forward side of a cross-member of a vehicle frame with a first gap being defined between the first structure and the cross-member. A second structure extends rearward from the cross-member with a second gap defined between the second structure and the cross-member. An attachment bracket fixed to the cross-member retains one of the first and second structures. The attachment bracket is configured to maintain one of the first gap and the second gap in a non-impacted state. In response to an impact event where a stationary barrier impacts forward of the first structure, impacting forces cause movement of the one of the first structure and the second structure relative to the attachment bracket thereby bringing at least the one of the first structure and the second structure into contact with the cross-member closing the corresponding one of the first gap and the second gap.

  • Publication number: 20180118267
    Abstract: An off-center impact reinforcement structure includes a push arm and a first diagonals structure installed to elements of a frame of a vehicle structure. The push arm is coupled to the frame proximate an intersection of a first side member and a first cross-member and extends in a forward and laterally outboard direction from the intersection. The first diagonal structure extends rearward and laterally inboard from proximate the intersection toward a section of a second side member rearward of the first cross-member. The off-center impact reinforcement structure is configured such that during an off-center impact event in which a stationary barrier impacts against a front surface of the push arm during forward movement of the vehicle frame, impacting forces from the impact event are transferred through the push arm to the vehicle frame at the intersection and from the intersection to the first diagonal structure.
