  • Patent number: 10905266
    Abstract: A pillow structure includes a pillow, a buffering layer mounted in the pillow, a base plate mounted on a bottom of the buffering layer and received in the pillow, and elastic cushions mounted on the base plate and drawn by adjusting devices. The elastic cushions are mounted on the bottom face of the base plate to support and adjust the height of the pillow, such that the pillow has an optimum height to provide a comfortable sensation to a user when sleeping at a supine position and sleeping sideways. The elastic cushions are also mounted on the top face of the base plate to push the buffering layer of the pillow so as to support the user's head and neck.

  • Patent number: 10827848
    Abstract: A passive mattress spacer pad provides an intermediate layer of material which sits between the bottom of the mattress and the underlying mattress support. In some embodiments, the spacer may have peripheral length and width dimensions that are roughly between about 1 and 18 inches smaller than the size of the mattress and have a thickness of between about ¼ inch and about 4 inches. In some embodiments, the spacer pad is independent, and in others, it is integrally formed with the support or the mattress. The spacer provides a measure of lift or elevation to the center of the mattress while leaving some space or “gap” around the peripheral edges where it is easier for the bed maker to slide their hands and the bed linens beneath the mattress edge without having to lift the mattress entirely.

  • Patent number: 9027184
    Abstract: An acupressure pillow includes pressure members that are interconnected by an elastic member and arranged so that, when the user rests a body part (e.g., head or neck) on the pillow between the pressure members, the pressure members automatically adjust to accommodate the body part and produce pressure on the body part due at least in part to the elastic member, which biases the pressure members toward one another. Thus, the pressure exerted on the body part may have different vector components, including some pressure produced essentially perpendicular to the pillow surface on which the body part rests and some pressure produced at other angles due to the shape of the pressure members and the inward force on the pressure members produced by the elastic member.

  • Publication number: 20090288256
    Abstract: A headrest for protecting a hairstyle of a user including a base portion and a head-supporting portion extending substantially horizontally from an upper surface of the base portion. The head-supporting portion includes a support surface and at least three finger members that extend substantially vertically from a peripheral edge of the support surface. The first and second finger members are located opposite one another and extend upward past the cheeks of the user. The third finger member extends upward from the distal end of the support surface past the back of the head of the user.

  • Patent number: 7568248
    Abstract: The invention provides a pillow capable of having the height thereof adjusted automatically so that the height of the back of the head of a user in a face-up lying position is slightly higher than his/her back, and also capable of having the height thereof varied automatically between a face-up lying position and a side lying position. A hollow portion 8 having a biasing mechanism 9 disposed therein is formed in a head placement member 3, and when the head is placed face-up on the head placement member 3, the hollow portion 8 is depressed so that the distance between the lowermost portion of the head and the bottom member 2 is in the range of 10 mm to 30 mm. The biasing mechanism has X-shaped links 11 disposed laterally spaced apart in the hollow portion 8. Each X-shaped link is composed by pivotally connecting a first link member 12 slanted upward toward the front and a second link member 13 slanted upward toward the rear by an intermediate link shaft 16.

  • Patent number: 7185378
    Abstract: An adjustable support/pad that retains any shape to which it is configured and which may be reshaped to serve another purpose. The support/pad has at least one pliable coil spring in the shape of a flexible tube capable of being bent into multiple positions and holding any of the positions until it is again bent. The coil spring is embedded in a deformable cushion to provide comfort of the body wherever the support/pad is applied. The adjustable support can be made into a neck supporting pillow, or a cushion adapted to be removably attached to the back of a chair, to support the back of a seated user.

  • Patent number: 6101651
    Abstract: A novel pillow core is made of plastic springs. A plurality of springs are connected together by a plastic link frame to form an actual pillow shape. The pillow core made of the plastic springs has strong supporting capacity, good elasticity and ventilation, and eliminates areas of heat concentration. It can easily be made into different sizes and can accommodate the neck portions of different users. In addition, it is easy to carry about and eliminate the necessity for cleaning and drying. Moreover, it saves raw materials such as feathers or silk cotton and the like, and shows excellent quality with reasonable prices.

  • Patent number: 5313678
    Abstract: A pillow adapted to support the head of a user includes a core having an axis extending through a central section and opposing end sections. The central section has a thickness adapted to support the head of a user and a length generally equivalent to the width of the user's head. The end sections are bent from the central section and are generally coextensive in a common direction to provide the core with a U-shaped configuration. Portions of the core define a slit extending into the core and a spring is disposed in the slit to extend through the central section and into each of the end sections. The spring has properties for biasing the end sections toward each other to provide a snug fit relationship with the ears of the user and thereby attenuate environmental sound. Speakers can also be placed in the slit to accommodate transmission of audio sound to the ears of the user. The pillow can be provided with a pillow case surrounding the core and a tote bag permanently attached to the pillow case.
