Abstract

A vehicle rocker panel torsion lever configured to reduce intrusion in the event of a side impact, the vehicle rocker panel torsion lever including a rigid elongated member including a first end and a second end, the first end configured to be fixedly coupled to a rocker panel of a vehicle, the second end free-floating within a cavity defined by a B-pillar of the vehicle, the rigid elongated member configured to translate a linear external side-impact applied to the B-pillar to a rotational force applied to the rocker panel.

First claim

What is claimed is:

1 . A vehicle including cantilevered lever mechanism configured to reduce intrusion in the event of a side impact, the vehicle comprising:
at least one rocker panel; a pillar including structure defining a cavity; and an elongated member being coupled to the at least one rocker panel as a cantilevered beam, the elongated member including a first end and a second end, the first end configured to be fixedly coupled to the rocker panel of the vehicle, the second end free-floating within the cavity defined by the pillar of the vehicle, the elongated member configured to translate a linear external side-impact applied to the pillar to a rotational force applied to the rocker panel, wherein the pillar comprises a first component coupleable to an inside surface of the at least one rocker panel and an inside surface of a component of a vehicle body, and a second component coupleable to an outside surface of the at least one rocker panel and an outside surface of the component of the vehicle body, wherein the first component and the second component define the cavity of the pillar, wherein the elongated member is a rocker panel torsion member, wherein said elongated member comprises at least a first member, wherein the first member is fixedly coupled to an exterior vertical surface of the at least one rocker panel at a first end, wherein the first member extends vertically from said exterior vertical surface of the at least one rocker panel, wherein external dimensions of a second end of the first member are located within a space defined in the second component of the pillar, wherein the first member is one single piece.

2 . The vehicle of claim 1 , further comprising a battery pack positioned below a passenger cabin in proximity to the at least one rocker panel.

3 . The vehicle of claim 1 , wherein the pillar comprises a first component coupleable to an inside surface of the at least one rocker panel and a second component coupleable to an outside surface of the at least one rocker panel, wherein the first component and the second component define the cavity of the pillar.

4 . The vehicle of claim 1 , wherein the elongated member is at least one of spot welded, bolted, screwed, riveted or adhered to the at least one rocker panel.

5 . The vehicle of claim 1 , wherein elongated member comprises a first member and a second member.

6 . The vehicle of claim 5 , wherein at least a portion of the elongated member has a shape with external dimensions shaped and sized to fit within a space defined by the cavity of the pillar.

7 . The vehicle of claim 6 , wherein the first member has a trapezoidal shape.

8 . The vehicle of claim 1 , wherein the elongated member is coupled to at least two surfaces of the at least one rocker panel.

9 . The vehicle of claim 1 , wherein the elongated member is constructed of at least one of steel, aluminum, fiber reinforced plastic, polymer, or foam.

10 . The vehicle of claim 1 , wherein the elongated member is formed by a method of at least one of forging, pressing, extruding, casting, or molding.

11 . A vehicle rocker panel torsion lever configured to reduce intrusion in the event of a side impact, the vehicle rocker panel torsion lever comprising:
an elongated member including a first end and a second end, the first end configured to be fixedly coupled to a rocker panel of a vehicle as a cantilevered beam, the second end free-floating within a cavity defined by a pillar of the vehicle, the elongated member configured to translate a linear external side-impact applied to the pillar to a rotational force applied to the rocker panel, wherein the pillar comprises a first component coupleable to an inside surface of the rocker panel and an inside surface of a component of a vehicle body, and a second component coupleable to an outside surface of the rocker panel and an outside surface of the component of the vehicle body, wherein the first component and the second component define the cavity of the pillar, wherein the elongated member is a rocker panel torsion member, wherein said elongated member comprises at least a first member, wherein the first member is configured to be fixedly coupled to an exterior vertical surface of the rocker panel at a first end, wherein the first member is arranged to extend vertically from said exterior vertical surface of the rocker panel, wherein external dimensions of a second end of the first member are configured to be located within a space defined in the second component of the pillar, wherein the first member is one single piece.

12 . The vehicle rocker panel torsion lever of claim 11 , wherein at least a portion of the elongated member has a shape with external dimensions shaped and sized to fit within a space defined by the cavity of the pillar.

13 . The vehicle rocker panel torsion lever of claim 12 , wherein at least a portion of the elongated member has a trapezoidal shape.

14 . The vehicle rocker panel torsion lever of claim 11 , wherein the elongated member comprises a first member which defines a weight saving aperture.

15 . The vehicle rocker panel torsion lever of claim 12 , wherein the elongated member comprises a first member and a second member which are coupled together by at least three distinct coupling points.

16 . The vehicle rocker panel torsion lever of claim 11 , wherein the elongated member is configured to be coupled to at least two surfaces of the rocker panel.

17 . The vehicle rocker panel torsion lever of claim 11 , wherein the elongated member is constructed of at least one of steel, aluminum, fiber reinforced plastic, polymer, or foam.

18 . The vehicle rocker panel torsion lever of claim 11 , wherein the elongated member is formed by a method of at least one of forging, pressing, extruding, casting, or molding.

19 . A vehicle body configured to reduce intrusion in the event of a side impact, the vehicle body comprising:
a pair of rocker panels; a pair of components; a pillar structure comprising:
a first pair of pillars positioned on a forward half of the vehicle and extending between the pair of rocker panels and the pair of components;
a second pair of pillars positioned on a rear half of the vehicle and extending between the pair of rocker panels and the pair of components;
a third pair of pillars positioned between the first pair of pillars and the third pair of pillars and extending between the pair of rocker panels and the pair of components of; and
a pair of elongated members, each elongated member including a first end and a second end, the first end configured to be fixedly coupled to a first rocker panel of the rocker panels, the second end free-floating within a cavity defined by the pillar structure, the elongated member being coupled to first rocker panel as a cantilevered beam, the elongated member is configured to translate a linear external side-impact applied to the pillar structure having the cavity defined therein to a rotational force applied to the first rocker panel, wherein the pillar structure comprises a first component coupleable to an inside surface of the first rocker panel and an inside surface of the component of the vehicle body, and a second component coupleable to an outside surface of the first rocker panel and an outside surface of the component of the vehicle body, wherein the first component and the second component define the cavity of the pillar structure, wherein the elongated member is a rocker panel torsion member, wherein the elongated member comprises at least a
