Abstract: A battery tray for a vehicle includes a tub having a base, a first side wall connected to the base, and a second side wall connected to the base and disposed opposite the first side wall. The tub includes a first portion with a first strength, the first portion extending from the first side wall through the base to the second side wall, and a second portion with a second strength, the second portion extending from the first side wall through the base to the second side wall. The second strength is greater than the first strength. The first portion is welded to the second portion prior to forming the tub.

Abstract: A battery tray for a battery powered vehicle includes a battery tray having a side wall. An impact absorbing structure is connected to the side wall. The impact absorbing structure includes at least one roll-formed member fixed to the side wall. The at least one roll-formed member is created from a single metal plate and includes a first plate portion roll-formed to create a first cavity and having a first flange created in a member central wall of the first plate portion. The first flange is fixed to the first plate portion. A second plate portion is roll-formed to create a second cavity and has a second flange at an end of the second plate portion fixed to the member central wall. A roll-formed U-shaped attachment member is fixed to the at least one roll-formed member.

Abstract: A side rail assembly connected to a battery tray in a motor vehicle includes a side impact rail having a first portion with a first strength, a second portion with a second strength, the second portion spaced apart from the first portion, and a third portion with a third strength, the third portion connected to the first portion and the second portion. The third strength is greater than the first strength and is greater than the second strength.

Abstract: A battery tray assembly for a battery powered vehicle includes a tub having a bottom wall connected with a side wall. A side rail assembly is connected to the side wall of the tub. A lower impact rail is connected to the side rail assembly. The lower impact rail extends beyond the bottom wall of the tub. The lower impact rail is removably connected to the side rail assembly by a fastener.

Abstract: An adjustable bumper, adapted for supporting closure panels on a vehicle, is described. The bumper incorporates a shape memory polymer portion, which may be readily permanently reshaped by the steps of: heating above its transition temperature, deforming by application of a load, and cooling, while still under load, below its transition temperature. This behavior is exploited to enable adjustment of the adjustable bumper so that it may provide the desired closure panel support while accommodating vehicle to vehicle variations in the fit of the closure panel and the vehicle body.
