Embodiment Construction

[0029] Reference will now be made in detail to several examples of the present disclosure which are illustrated in the accompanying drawings. Wherever possible, the same or similar reference numerals are used in the drawings and the description to denote the same or similar components or steps. The drawings are in simplified form and not to precise scale. Directional terms such as top, bottom, left, right, upper, above, above, below, below, rear and front may be used with respect to the drawings for convenience and clarity only. These and similar directional terms should not be construed to limit the scope of the present disclosure in any way. Referring now to the drawings, wherein like reference numerals correspond to like or similar parts throughout the views, figure 1 is a schematic cross-sectional side view of a conventional vehicle seat 100 and a passenger 102 in a taxiing position during a vehicle crash event, figure 2 is a schematic cross-sectional side view of a ve...

Abstract

A vehicle seat for a vehicle is provided. The vehicle seat includes a first foam and a second foam. The first foam has a rate sensitivity as measured in accordance with a modified ISO 3886 / 1 standardwhich can accommodate a slow speed test with a static strain rate of about 0.001 second<-1> and a high speed test with a dynamic strain rate of about 100 second<-1> such that the dynamic versus staticstrain rate increases by at least 200%, and the first foam is temperature stable such that the glass transition temperature of the first foam is less than or equal to zero degrees Celsius and a change in tan delta of less than or equal to 35% from a median value measured over a temperature range of from about negative 20 degrees Celsius to about 60 degrees Celsius.

Description

technical field [0001] The present disclosure relates to a vehicle seat that provides a temperature-stabilized, velocity-sensitive support. Background technique [0002] This Introduction generally presents the context of the disclosure. The work of the presently named inventors (to the extent they are described in this Introduction) and aspects of the description that might not have been considered prior art at the time of filing are neither expressly nor implicitly considered part of the present disclosure current technology. [0003] Vehicles (eg, automobiles) include vehicle seats. For example, a vehicle may include several rows of vehicle seats. The vehicle operator may occupy the front vehicle seat, while the passenger may occupy the other vehicle seat. A vehicle seat is intended to provide a comfortable seat for a vehicle occupant while providing adequate support for controlling the occupant's position in the event of a vehicle crash. [0004] In the event of a f...
