1. Field of the Invention
The invention relates to a seat cushion, more particularly to a seat cushion that is designed according to the contour of a human body and that has a vibrating unit for massaging the groin portion of a human body.
2. Description of the Related Art
Generally, a seat cushion is used to provide comfort for the user when seated on an office chair or a vehicle seat. However, such effect is limited since the thighs and the buttocks of the user are likely to suffer a definite degree of pressure attributed to long term sitting on the conventional seat cushion, which in turn can affect blood circulation in the user's body.
Therefore, the object of the present invention is to provide a seat cushion that is capable of massaging the groin portion of a human body so as to promote blood circulation of the blood vessels near the groin portion so that irregular blood circulation can be reduced and so as to promote good health.
According to this invention, a seat cushion comprises a cushion body and a vibrating unit. The cushion body has a rear section adapted to press against the buttocks of a user, and a front section extending frontwardly from the rear section. The front section includes two spaced-apart thigh support portions, and a protruding portion projecting upwardly between the thigh support portions and adapted to press against the groin portion of the user. The vibrating unit is disposed in the protruding portion for massaging the groin portion of the user so as to promote blood circulation.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
Referring to FIGS. 1 to 4, the preferred embodiment of a seat cushion according to the present invention is shown to comprise a cushion body 3, a vibrating unit 4, a first heating unit 51, a second heating unit 52, and a controlling unit 6.
The cushion body 3 is designed ergonomically, and is made of a foam material. The cushion body 3 has a rear section 31 adapted to press against the buttocks 21 of a user 2, and a front section 32 extending frontwardly from the rear section 31. The rear section 31 is enlarged rearwardly and outwardly from the front section 32, and has a height that increases upwardly and rearwardly from the front section 32. The front section 32 includes two spaced-apart thigh support portions 321 for supporting two thighs 22 of the user 2, and a protruding portion 322 projecting upwardly between the thigh support portions 321 and adapted to press against the groin portion of the user 2.
An outer surface of the protruding portion 322 may be designed with uneven concave and convex patterns to provide the seat cushion of the present invention with a better air circulation effect. To manufacture the cushion body 3, the protruding portion 322 of the front section 32 and the other portions of the cushion body 3 may be made of foam materials with different densities according to the different supporting forces required by different portions of the cushion body 3.
The vibrating unit 4 (see
The first heating unit 51 (see
The second heating unit 52 (see
Since the structure of each of the first and second heating units 51, 52 is not pertinent to the present invention, and since many structural designs of the heating devices are available in the market that can be used in the seat cushion of this invention, a detailed description of the same will be dispensed with herein for the sake of brevity.
The design of the seat cushion of the present invention does not necessarily include both the first and second heating units 51, 52 in the cushion body 3. In practice, the cushion body 3 may be provided with only the first or the second heating unit 51, 52 depending on actual requirements.
The controlling unit 6 (see
