摘要： An apparatus for protecting an elongated structural support (12) from impact comprises an elongated impact protection component (14, 16) which has a top, a base, and a peripheral side wall (52). The side wall (52) has a rear portion that is configured to mate with the structural support (12) so as to seat the component (14, 16) in an installed position adjoining the structural support (12), and surrounds an air chamber (56). The side wall (52) further has a front portion configured to deflect inwardly toward the rear portion so as to reduce the volume of the air chamber (56) upon the impact of a vehicle or the like, and thereby to protect the structural support (12) from the impact. The front portion of the side wall (52) has inner and outer surfaces with undulating contours (50) that define projections at said inner surface and corresponding indentations at said outer surface. According to the present invention, the undulating contours (50) define a plurality of discreet, spaced-apart indentations at the outer surface and a corresponding plurality of discreet, spaced-apart projections at the inner surface.

摘要： An apparatus for protecting an elongated structural support from impact, said apparatus comprising: a plurality of elongated impact protection components (14, 16) configured to fit together beside each other in installed positionss in which said components define transversely adjacent segments of an elongated impact protection body that surrounds the structual support (12); each of said components (14,16) having a peripheral side wall (52, 82) with a rear portion (82, 40) configured to mate with the structual support (12) upon movement of the component transversely into its installed position; each of said side walls (52, 82) surrounding a respective air chamber (56) and further having a front portion ( 52) configured to deflect inwardly toward said rear portion (82, 40) so as to reduce the volume of said respective air chamber (56) upon the impact of a vehicle or the like, and thereby to protect the structural support (12) from said impact.
