Rocker assembly insert with opposed crush channels

A vehicle rocker assembly comprising:

• a sill structure having an outer sill member attached along an inner sill member;
• a reinforcement insert disposed in a hollow interior between the outer and inner sill members, the reinforcement insert comprising an outer tubular section and an inner tubular section integrally formed together and disposed laterally adjacent to each other;
• and
• a crush control feature integrally disposed at a wall of the reinforcement insert and extending longitudinally along a length of the reinforcement insert,
• wherein the crush control feature is configured for a side impact force at the outer sill member to laterally deform the reinforcement insert in an accordion-style crush.

A vehicle rocker assembly comprising:

• an outer sill member;
• an inner sill member attached longitudinally along the outer sill member to define a hollow space between the inner and outer sill members;
• and
• a tubular insert disposed in and extending longitudinally along the hollow space, the tubular insert comprising an outer tubular section and an inner tubular section integrally formed together and disposed laterally adjacent to each other,
• wherein at least one of the outer tubular section or the inner tubular section includes an upper crush channel and a lower crush channel disposed at upper and lower walls of the respective outer or inner tubular section,
• wherein the upper and lower crush channels extend longitudinally along the tubular insert and are configured for a side impact force at the outer sill member to initiate lateral deformation of the tubular insert.
