Problems solved by technology

For example, in a cushion installed in a vehicle, the cushion is deformed due to input of vibration in a low-frequency band (for example, around 1 Hz) when the vehicle is driving slowly or changing lanes, resulting in lateral sliding or friction around the roller axis. Shaking sensation such as lateral shaking

Embodiment Construction

[0046] Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. figure 1 It is a top view showing the cushion pad 1 of the first embodiment of the present invention. In this embodiment, the cushion 1 mounted on a vehicle with vibration (especially an automobile) will be described. In addition, figure 1 The arrows U-D, L-R, and F-B respectively indicate the vertical, horizontal, and front-rear directions of the vehicle (not shown) equipped with the cushion 1 ( figure 2 , Figure 4 and Figure 7A The same in B).

[0047] Such as figure 1 As shown, the cushion pad 1 is a base material integrally formed of soft polyurethane foam (a kind of foamed synthetic resin material), and is provided with a supporting part 2 for supporting the buttocks and the back of the thigh of the occupant H; And the side support parts 5 are arranged on both sides of the support part 2 in the left-right direction (arrow LR direction). The side support p...

Abstract

The invention provides a cushion pad that reduces the wobbling feeling. Regarding the test piece sampled from a core portion (22, 23, 32, 33), the measured deflection under a load of 100 N during compression is equal to or less than 30 mm. The measured static spring constant under a load of 300 N at a pulling rate of 20 mm/minute is equal to or less than 25 N/mm. In the case of a vibration input in a low frequency band in the lateral direction, the compressive stress in the vertical direction due to the weight of a seated person (H) and the tensile stress due to the vibration input in the lateral direction act on the support portion (2). The direction (gradient) of the resultant force as a combination of the compressive stress and the tensile stress can be closer to the vertical direction. This allows reducing the wobbling feeling.

Description

Technical field [0001] The present invention relates to a cushioning pad, in particular to a cushioning pad capable of suppressing shaking. Background technique [0002] In cushioning cushions used in seats such as seats or furniture such as chairs equipped in vehicles, ships, airplanes, and the like, passengers sometimes feel a sense of lateral shaking. For example, in a cushion installed in a vehicle, because the vehicle inputs low-frequency (for example, about 1 Hz) vibration when the vehicle is driving slowly or changing lanes, the cushion will be deformed, which will cause lateral sliding or around the roller shaft. A sense of shaking such as lateral shaking. Shaky feeling is the main factor affecting driving stability. In order to suppress this feeling of shaking, there is a prior art (Patent Document 1) that sets tan δ relative to low-frequency vibration within a predetermined range.
