[0001] The present invention relates to an improved seat structure of a tourist coach and, more particularly, to a seat structure capable of quickly changing from a double seat into a single seat or vise versa.
[0002] A plurality of single seats
[0003] One object of the present invention is to provide an improved seat structure of a tourist coach, wherein the structure of a backrest is properly designed so that a seat can be used as a double seat or a single seat. Moreover, the change between the single seat and the double seat is easy so that carmen or passengers can conveniently perform the operation. Therefore, the number of seats in a tourist coach can vary according to the number of passengers. If there are many passengers, double seats can be used to accommodate them. If there are only a few passengers, each passenger can have a comfortable and luxurious single seat.
[0004] To achieve the above object, a seat of the present invention comprises a cushion, a pair of backrests, a pair of bolsters, and a pair of armrest pads. The cushion has a width of double seat. Both the backrest and the bolster have a width of single seat. The front face of each of the bolsters has a concave arc portion, and the back face of each of the bolsters has a slanting arc portion. The bolsters can be turned 180 degrees. The bolster joins the backrest through a fixing device. A joining device is disposed at the adjoining position of the two backrests. Each side of the cushion has an armrest, which joins a pad to form the armrest pad. The pad and the armrest are joined together through a turn control device so that the pad can be turned 90 degrees to form a projective state of a wide face of the pad, hence facilitating use of a single seat. Use state of a double seat can be obtained by restoring the armrest pads.
[0005] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:

[0025] As shown in
[0026] The turn control device
[0027] To sum up, in the present invention, the bolsters and the pads of the armrest pads are exploited so that change between a double seat and a single seat can be accomplished with minimal actions. The double faces of the bolsters can be utilized so that the head of a passenger can be placed thereon more comfortably. The bolsters are matched with the positioning of the press fasteners so that both the use states of a single seat and a double seat can be accomplished. Additionally, the turn of the pads can be exploited to shrink part space of the cushion so that a passenger can seat more comfortably on the seat used as a single seat.
[0028] Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
