Embodiment Construction

[0022] It has been determined that pure plastic parts will not meet all criteria. (ECE42, RCAR, FMVSS Chapter 581, IIHS 10kph test, and deformable obstacle impact test). Therefore, the current trend is to use metallic systems. Metal systems, however, are designed to be extra safe for European standards. Disclosed are lightweight energy absorbing components (eg, hybrid plastic-metal energy absorbing systems) that can be used in several combinations to meet various global regulations. In other words, the energy absorbing assemblies of the present disclosure can be designed to meet desired criteria. A different design is not required. This system can reduce manufacturing costs because one design can be used to meet each standard. In other words, energy absorbing components can be tuned and used in several combinations to meet global damage tolerance regulations and regulatory standards for various global platforms.

[0023] In various embodiments, the present invention discl...

Abstract

An energy absorbing assembly (10) for impact energy absorption can comprise: an elongated plastic member (20) having a major axis, a first side and a second side, comprising a central portion disposed between a first end portion and a second end portion, the second side defines a channel (210) extending from the first end portion to the second end portion; and an elongated insert (30) having a front, edges, tips, and a rear, wherein the insert is configured to flex upon impact, and is removably friction fit within the channel such that the plastic member surrounds the front, and greater than or equal to 50% of the edges and tips. The energy absorbing assembly can be configured to attach to a vehicle to absorb energy absorption impact. A vehicle can comprise: a vehicle rail and the energy absorbing assembly attached to the vehicle rail.

Description

technical field [0001] The present disclosure generally relates to an energy absorber for use in a vehicle, eg, to reduce injury (eg, to passengers, pedestrians, etc.) and to reduce damage to the vehicle. Specifically, the present disclosure relates to a metal-plastic hybrid energy absorbing directional system capable of absorbing low and medium velocity impact energy (impact energy). Background technique [0002] Regulations governing low-speed damage tolerance requirements for automobiles vary around the world. In general, these regulations can be divided into two categories: the first for continental Europe and the second for the United States. Although the technology used is different, the Pacific Rim also adheres to Eurocodes and has slightly more relaxed regulations on shocks. This means that energy absorption systems designed to meet European and Pacific Rim regulations are different from those used in the US market. [0003] In Europe and the Pacific, Economic Com...
