Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to covers for seats and, more particularly, to ventilated seat covers.

2. Description of the Prior Art

When a person sits in a seat, there is often a build up of perspiration on portions of the person that are most close to the seat. This is especially true in hot summer months. It is also especially true in vehicles, and most especially vechicles that are not air conditioned, such as construction vehicles and tractors. In such vehicles, the build up of perspiration may be in such great quantity that the clothing of the vehicle operator becomes wet. To reduce perspiration build up in such conditions, throughout the years, a number of innovations have been developed relating to seat ventilation, and the following U.S. patents are representative of some of those innovations: U.S. Pat. No. 4,413,857, U.S. Pat. No. 4,981,324, U.S. Pat. No. 4,997,230, U.S. Pat. No. 5,370,439, U.S. Pat. No. Design 267,523, and U.S. Pat. No. Design 343,326. More specifically, the devices disclosed in each of U.S. Pat. Nos. 4,413,857, 4,981,324, 4,997,230, and 5,370,439 vary from one another in numerous ways. However, those devices have a number of common characteristics as well. For example, each of those devices connects to a source of forced air to provide forced-air ventilation. Moreover, each of those devices has only one location for connecting to a source of forced air. As a result, if the flexible air hose that runs between a source of forced air and the seat is connected to the seat in an inconvenient location, the hose may get in person's way, and avoiding such inconvenience does not seem to be contemplated. To avoid the problem of an inconveniently located air hose connection, it would be desirable if a ventilated seat cover device included a number of optional connection sites for an air hose.

Each of the devices in U.S. Pat. Nos. 4,413,857, 4,981,324, 4,997,230, and 5,370,439 share another common characteristic. With each device, a seat portion and a back portion are permanently connected to each other. There are some vehicles, however, which have seats but do not have back portions to the seats. For such vehicles, it would be desirable if a ventilated seat cover device did not include a back portion.

As a matter of interest, each of U.S. Pat. No. Design 267,523, and U.S. Pat. No. Design 343,326 discloses a passive seat cover that does not include a source of forced air.

Still other features would be desirable in a ventilated seat cover device. For example, for ventilated seat covers that are employed outdoors, often dusty conditions are prevalent. To prevent dust from entering the ventilated seat cover, it would be desirable if a source of forced air had an intake air filter. In addition, electrical power in motor vehicles is usually based on a DC battery. In this respect, it would be desirable if a ventilated seat cover employs a DC battery for powering a blower. Some motor vehicles, especially vehicles that have enclosed cabs, often have air conditioning systems that have a forced air blower. In this respect, it would be desirable if a ventilated seat cover had a option of deriving forced air from a blower in an in-place air conditioning system.

There may be times when it is desirable to use a ventilated seat cover. On the other hand, there :may be other times when it is not desirable to use a ventilated seat cover. In this respect, it would be desirable if a ventilated seat cover were provided that is easily put on or removed from a vehicle seat.

In a passenger vehicle, there are often two persons seated on front seats, a driver and a passenger. To avoid the need for two blowers to ventilate two seats, it would be desirable if an adaptor were provided that enables two ventilated seat covers to be ventilated by one blower.

Thus, while the foregoing body of prior art indicates it to be well known to use ventilated seat covers, the prior art described above does not teach or suggest a ventilated seat cover apparatus which has the following combination of desirable features: (1) includes a number of optional connection sites for an air hose; (2) optionally, may or may not include a back portion; (3) has an intake-air filter; (4) employs a DC battery for powering a blower; (5) has an option of deriving forced air from a dedicated blower a blower in an in-place air conditioning system; (6) is easily attached to or removed from a vehicle seat; and (7)enables two ventilated seat covers to be ventilated by one blower. The foregoing desired characteristics are provided by the unique ventilated seat cover apparatus of the present invention as will be made apparent from the following description thereof. Other advantages of the present invention over the prior art also will be rendered evident.
