Abackrest 5 of thesingle seat 1 is wider and has two wide armrests 7, while the double seat 2 has a pair of narrow backrests 6 to share the width of the cushion 4. Each side of the backrest 4 joins aflat armrest 8. Two persons can sit on the double seat 2, while only one person can sit on thesingle seat 1, and this is unchangeable. Therefore, the arrangement of seats of a tourist coach is fixed and cannot vary according to the number of passengers. - 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.
- 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.

- FIG. 13 is a perspective view showing the action of the present invention.
- As shown in FIGS.2 to 13, a
seat 10 of a tourist coach of the present invention comprises acushion 11, a pair ofbackrests 12, a pair ofbolsters 13, and a pair ofarmrest pads 14. Thecushion 11 of theseat 10 has a width of double seat, and is elevated by aseat foot 15. Thebackrests 12 are perpendicularly joined with the rear end of thecushion 11. Thebackrest 12 has a width of single seat. - The
bolster 13 also has a width of single seat. Thebolster 13 has afront face 16 and aback face 17 as wide faces. Thebolster 13 is joined on thebackrest 12. Thefront face 16 has aconcave arc portion 18, and theback face 17 has aslanting arc portion 19 tilting toward the adjacent bolster. When thecushion 11 is used for a double seat, the front faces 16 face forwards. When thecushion 11 is used for a single seat, the back faces 17 face forwards. If a single seat is to be formed, thebolsters 13 are turned 180 degrees, and theslanting arc portions 19 of theback faces 17 of thebolsters 13 are used as a special arc face. That is, the twobolsters 13 form a shape with a recessed middle portion. This describes the change from a double seat shown in FIG. 3 to a single seat shown in FIG. 4. - The
armrest pads 14 have a pair ofarmrests 21 and a pair ofpads 22. Thearmrests 21 are joined at two sides of thecushion 11. Thearmrests 21 can join theseat foot 15 if only the lower ends of thearmrests 21 are fixed at appropriate positions. Thepads 22 are joined on thearmrests 21. Thepads 22 havenarrow face portions 23 andwide face portions 24. Thepads 22 can be turned. When thecushion 11 is used for a double seat, thenarrow face portions 23 face upwards. When thecushion 11 is used for a single seat, thewide face portions 24 face upwards. - As shown in FIGS. 5 and 6, a
fixing device 30 is disposed between thebolster 13 and thebackrest 12. Thefixing device 30 comprises aninsertion pole 31, abushing 32, and apress fastener 34. Theinsertion pole 31 is joined at the center of the bottom face of thebolster 13. Thebushing 32 is joined in thebackrest 12. Theinsertion pole 31 is inserted into thebushing 32 and then positioned by thepress fastener 34. - As shown in FIGS. 8 and 9, the
bushing 32 does not protrude out of the top face of thebackrest 12, and thepress fastener 34 is joined at the upper end of thebushing 32. Thepress fastener 34 has aninner ring 35 and anouter ring 36. Theinner ring 35 has apress head 37. Theouter ring 36 has a throughhole 38. Thepress head 37 protrudes out of the throughhole 38. A smallresilient part 39 is disposed between theinner ring 35 and theouter ring 36. The smallresilient part 39 is a small spring. The smallresilient part 39 is positioned at agap 40 of theouter ring 36. Theinner ring 35 can be used to lock anannular groove 41 of theinsertion pole 31. If theinsertion pole 31 has a plurality ofannular grooves 41 thereon, thepress fastener 34 can be used to adjust the position of theinsertion pole 31, hence adjusting the height of the bolster 13. Aminiature portion 33 is disposed near the lower end of theinsertion pole 31. A mainresilient part 42 is joined between theminiature portion 33 and the inner bottom face of thebushing 32. The mainresilient part 42 is a compression spring. When thepress fastener 34 releases its restriction to theinsertion pole 31, theinsertion pole 31 will automatically spring upwards to facilitate the adjustment of the bolsters 13 from a double seat to a single seat or vice versa. - The
backrests 12 can be turned over. The mechanism letting the backrests be turned over is a standard equipment and has nothing to do with the present invention. The seat of the present invention is basically a double seat, and is primarily seated by two persons side by side. Each of the backrests has a hydraulic supporting structure for adjusting the slanting angle of the backrest. When the seat is used as a single seat, separate adjustment cannot be performed. The two backrests need to be adjusted together to let them move synchronously. One of the hydraulic supporting structures can be temporarily disabled. This control action can be performed and set by the driver or the carmen. Additionally, because the two backrests move synchronously, a joiningdevice 25 is required to join the two backrests together so that they can be turned over simultaneously. As shown in FIG. 7, the joiningdevice 25 is an inverselyU-shaped fastener 26 inserted into the insertion holes 27 of the twobackrests 12. However, the joiningdevice 25 is not limited to the inversely U-shaped fastener. Any structure capable of joining the two backrests can be used as the joiningdevice 25. If smoothness is required, a thin pad 28 shown as a dotted line in FIG. 6 can cover over the backrest. - As shown in FIGS. 11 and 12, a
turn control device 50 is disposed in thearmrest pad 14. Theturn control device 50 can be used to let thepad 22 be turned within the range of 90 degrees. Theturn control device 50 comprises aninner bushing 51 and anouter bushing 52. Theinner bushing 51 joins the armrest 21, while theouter bushing 52 joins thepad 22. Theouter bushing 52 is sleeved onto theinner bushing 51. Theinner bushing 51 joins anannular sleeve 53 outside. Theannular sleeve 53 has an embeddingportion 54. Theouter bushing 52 has asleeving portion 55. Thesleeving portion 55 and the embeddingportion 54 are joined and positioned. Aresilient part 56 in theinner bushing 51 can be joined at an appropriate position, preferably being the outer end face, of theouter bushing 52. Theresilient part 56 is a long spring. - The
turn control device 50 mainly exploits a dual bushing to support thepad 22. Theouter bushing 52 and thepad 22 are connected together. Thepad 22 can be pulled outwards to stretch theresilient part 56 so that the tooth-shapedsleeving portion 55 no longer tightly press the embeddingportion 54 of theannular sleeve 53. Therefore, theouter bushing 52 can be turned. Because thenarrow face portions 23 of thepads 22 face upwards when used for a double seat, thepads 22 can only be turned 90 degrees inwards and fixed there. The sleeving portion and the embedding portion are then joined together to facilitate the placement of the elbows of a passenger when used for a single seat. The use state of a double seat can be accomplished by reversing the above actions. The actions of turning over the bolsters and the pads shown in FIG. 13 are exploited to achieve free change between a double seat and a single seat. - 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.
- 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.
