Abstract: The utility model provides an airbag for a pillow with adjustable height, wherein it is comprised: multiple airbag units arranged in stack, multiple supporting and connecting holes arranged in array in the opposite direction as the airbag units; two adjacent airbag units communicating through the said supporting and connecting holes; during the inflation or deflation process of the said airbag unit, the gas flows into or out of the airbag from the multiple supporting and connecting holes simultaneously, so that the inflation velocity of each part of the airbag unit is uniform, and the overall height of the airbag changes synchronously with the inflation or deflation. The utility model provides an airbag and a pillow for the height adjusting pillow, during the inflation or deflation process of the airbag unit, the overall height of the airbags changes synchronously with the inflation or deflation.

Abstract: The present utility model provides a pillow with adjustable height, which comprises a pillow body and an airbag; the pillow body is internally provided with a cavity for accommodating an airbag; the airbag is arranged on the lower bottom surface of the cavity and expands towards the direction close to the upper top surface of the cavity after inflation; the pillow body extends towards the direction close to the cavity at the connecting part between the side wall of the cavity and the upper top surface to form a thickened transition region. According to the pillow with adjustable height, when lying on the back and on the side, the pillow has better support strength to the neck and the head. There will be no obvious collapse feeling and the comfort level of users will be increased.

Abstract: The present invention provides a method for adjusting pillow height, which comprises the following steps: 1) Taking out the airbag from the pillow with adjustable height, applying a certain weight on the airbag, inflating and deflating the airbag, recording the airbag heights corresponding to the airbag under different air pressures, and obtaining the corresponding relations between the air pressures of the airbag and the heights; 2) During the process of adjusting the pillow height, the air pressure inside the airbag is read through a barometer, and the current height of the airbag is obtained through the corresponding relation between the air pressure and the height; 3) Stop inflating or deflating the airbag when the current height of the airbag is consistent with the target height. The present invention also provides a pillow for adjusting the height, which uses the method for adjusting the height of the pillow as described above.
