Kick down area enabler

Abstract

A vehicle rail assembly has an extending longitudinal rail with a kick down area. A kick down area enabler is positioned in the rail at the kick down area. The kick down area enabler includes a foot rest portion, an outer part portion and a kick down portion all contacting the rail. The outer part portion and kick down portion part are cantilevered from the foot rest portion via welding. The kick down area enabler provides additional energy absorption for the rail to prevent intrusion into a passenger compartment.

DETAILED DESCRIPTION

(6) Turning to the figures, a vehicle is illustrated and designated with the reference numeral 10. The vehicle 10 includes a passenger compartment 12 and a frame 14. The frame 14 includes a pair of rails 16. The rails are spaced laterally in a parallel relationship with respect to one another and extend longitudinally, forwardly, rearwardly, respectively. Each rail has a forward portion 18, a central portion 20 and a rear portion 22. In the illustrated embodiment, the forward portion 18 includes a kick down portion 24. The kick down portion 24 transitions from a higher vertical height to a lower vertical height via the rail.

(7) The rail assembly 14 includes an inner member 26 and an outer member 28. The inner member 26 generally has an overall C shape with a web 30 separating legs or sides 32, 34. The sides 32, 34 include a flange 36. The outer rail has an overall planar body 38. The planar body 38 includes outer flanges 40 that abut with flanges 36 to enable the inner 26 and outer 28 members to be connected via spot welding or the like with one another. Additionally, the outer member 28 may have various stampings 42, for reinforcement purposes, on the body 38.

(8) The kick back enabler 50 is positioned within the rail inner 26 and outer 28 parts at the kick down portion 24. The kick back enabler 50 includes a foot rest portion 52, a kick back portion 54 and an outer part portion 56. Foot rest portion 52 is U shaped with a pair of sidewalls 58 and 60 spaced apart by a web 62. The sidewalls 58 and 60 in side elevation having an overall triangular shape. The web has an open end 62 and a wall 64 closing off the end of the foot rest portion 52. The foot rest portion 52 is spot welded or the like to the rail 16. The foot rest portion 58 acts as an anchor in the foot rest area of the rail 16. It provides for enhanced deformation of the frame 14 or rail 16 in the foot rest area.

(9) The kick down portion 54 includes a sidewall 68 and a base 70. The sidewall 68 extends substantially perpendicular to the base 70. The sidewall 68 may have any desired configuration to mesh with the stamped portion of the inner member 26 of the rail 16. Additionally, a wall 72 is formed at one end of the kick down part 54. The wall 72 is formed adjacent to the wall 64 of the foot rest portion 52. The wall 72 is spot welded with the wall 64 or side wall 68 of the foot rest portion 52.

(10) The outer part portion 56 includes a sidewall 74 and a base 76. The sidewall 74 is elongated and extends longitudinally forward beyond the kick down portion 54. Additionally, the sidewall 74 tapers from a larger vertical portion into the smaller vertical portion inside the rail 16. The base 76 is substantially perpendicular to the sidewalls 74. Also, an end wall 78 is positioned adjacent the kick down end wall 72 and adjacent the foot rest end wall 64. The end wall 78 includes a bead weld connecting the outer wall portion 56 with the foot rest portion 52.

(11) The outer part portion 56 and the kick down portion 54 are spot welded with one another to form the integral kick down enabler 50. The outer wall portion side wall 74 as well as the kick down sidewall 68 are spot welded to the respective inner 26 and outer 28 members. Additionally, the bases 70, 76 may be spot welded to the rail 16. The end or wall 72, 78 of the kick down part and outer part are adjacent to the dash panel of the passenger compartment 12. Accordingly, these parts provide additional energy absorption for the rail 16 to prohibit dash panel intrusion.
