Neck supporter
View Patent ↗Provided is a neck supporter which is easy to use and which can reliably support the head of the wearer. The neck supporter includes an elongated main body providing said air-bag; an air injection valve that is provided in said main body to enable the air to be injected into said air-bag or discharged therefrom; connection sections (e.g., loops and hooks) that are provided on opposite surfaces in a vicinity of opposite ends of said main body to connect said opposite surfaces to each other; and a plurality of retaining portions (e.g., thermal compression bonding portions and through-holes) that are provided dispersedly as dots in series in a longitudinal direction of said main body to provide bonded portions between a front surface and a back surface of said main body.
1. A neck supporter configured to fit around a neck of a wearer and having an air-bag configured to receive air, said neck supporter comprising:
an elongated main body providing said air-bag, said elongated main body being provided with a bulge portion having a central area on a lower side curving downward so that a substantially central point is placed at a lowermost position;
an air injection valve that is provided in said main body to enable the air to be injected into said air-bag or discharged therefrom;
connection sections that are provided on opposite surfaces in a vicinity of opposite ends of said main body to connect said opposite surfaces to each other;
a plurality of retaining portions that are provided dispersedly as dots in series in a longitudinal direction of said main body to provide bonded portions between a front surface and a back surface of said main body, the plurality of retaining portions defining a boundary as a straight line connecting said retaining portions, the boundary extending along the longitudinal direction of the elongated main body, the boundary defining the elongated main body as a double inflated unit having:
an upper air-bag section defining a continuous chamber between both the front surface and the back surface of the main body and extending along the longitudinal direction of the elongated main body, the upper air-bag section disposed between the plurality of retaining portions and an upper side of the elongated main body, and
a lower air-bag section defining a continuous chamber between both the front surface and the back surface of the main body and extending along the longitudinal direction of the elongated main body, the lower air-bag section disposed between the plurality of retaining portions and the lower side of the elongated main body,
the double inflated unit configured to inflate in response to injection of air into said main body, so as to bring the bulge portion of said main body into contact with a chest of the wearer;
a length of the front surface in the longitudinal direction of said main body is longer than a length of the back surface in the longitudinal direction of said main body; and
a length of the front surface in a lateral direction of said main body is shorter than a length of the back surface in a lateral direction of said main body.
2. The neck supporter, as claimed in claim 1 , wherein:
said main body has a bulge portion, which curves downward in a vicinity of a central area of an upper side.
3. The neck supporter of claim 1 , wherein the boundary defines the elongated main body as a single double inflated unit having:
a single upper air-bag section extending along the longitudinal direction of the elongated main body and disposed between the plurality of retaining portions and an upper side of the elongated main body; and
a single lower air-bag section extending along the longitudinal direction of the elongated main body and disposed between the plurality of retaining portions and the lower side of the elongated main body.
4. The neck supporter of claim 1 , wherein a distance between the upper side of the elongated main body and the plurality of retaining portions is larger than the distance between the lower side of the elongated main body and the plurality of retaining portions.
5. The neck supporter of claim 1 , wherein the plurality of retaining portions are disposed in an L-shape in proximity to the lower side of the elongated main body.
