Description

Technical Field

[0001] The utility model relates to a pressure-relieving mattress, belonging to the technical field of mattresses. Background Art

[0002] Ordinary bed boards are inelastic flat plates made of steel or wood, but the human body is curved, so when sleeping, whether lying on the side, back, or stomach, the most protruding parts of the body are in the most severe contact with the flat bed, resulting in a strong sense of local pressure. Therefore, the whole sleeping process requires constant tossing and turning to reduce body fatigue, but it also affects the quality of sleep. To this end, the industry has developed a variety of mattresses. For example, the Chinese utility model patent with authorization announcement number CN217987146U discloses a natural antibacterial double-layer partitioned mattress, and specifically discloses a breathable top layer, an antibacterial fiber layer, a rebound layer, a first spring layer, a first sound-absorbing layer, a second spring layer, a second sound-absorbing layer and a bottom layer arranged from top to bottom. The caliber of the springs in the first spring layer is smaller than the caliber of the springs in the second spring layer. This type of mattress only relieves pressure on the human body by setting a spring layer. The direction of the spring force is always upward, and the pressure relief effect is poor.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In the present invention, when a person lies on the first mattress layer, the first mattress layer changes and transmits force to the upper plate of the pressure relief mechanism. The upper plate tilts according to the direction of the force, and the tilted upper plate applies force to the vertical plate of the ribs. The vertical plate portion drives the second arc portion to move in the direction of the force. The second arc portion causes the first arc portion and the inclined plate portion to deform and generate elastic force. This elastic force supports the person, allowing the first mattress layer to better fit the person and achieve a pressure relief effect. As a result, the present invention can provide multi-angle pressure relief support for the person, better fit the person, and have the advantage of better pressure relief effect.

[0013] 2. In the present invention, the recovery performance of the pressure relief mechanism can be enhanced by the auxiliary rebound mechanism. Compared with the usual single spring, multiple spiral ribs can provide more elastic force to assist the pressure relief mechanism in resetting, and at the same time can prevent the ribs from breaking due to excessive force applied.
