referring first to fig1 an automobile 1 comprises a rear seat 2 for two or three passengers , the seating part 3 of said rear seat 2 being continuous , whilst the bottom part of the back rest 4 is split to accomodate a conventional fold - down arm rest . the space provided for said conventional arm rest accomodates a refrigerating device 5 occupying the entire space provided for said conventional arm rest , said refrigerating device 5 having insulated walls and a front opening for access , an evaporator 6 being incorporated inside side device near the roof thereof and said front opening being closed or opened by a front cover 7 or 7 &# 39 ;. a fold - down arm rest 8 is fixed to the bottom edge 18 of said refrigerating device 5 , the upper surface 9 of said arm rest 8 being integrated into the upholstered back rest 4 of said rear seat 2 when said arm rest 8 is folded up . the cover 7 or 7 &# 39 ; of said refrigerating device 5 may be opened or closed or removed from said refrigerating device 5 , said cover 7 or 7 &# 39 ; being attached to said refrigerating device 5 by hinge means . said cover may be the upper part ( cover 7 ) or the entire front ( cover 7 &# 39 ;) of the front wall 32 of said refrigerating device 5 . fig1 also depicts , by a broken line , a refrigerant line 10 to a refrigeration device 12 accomodated in the trunk 10 of automobile 1 . the refrigerating device 5 shown in fig2 and representing another embodiment of the present invention is of the same design and of the same size as the refrigerating device 5 in fig1 if the design and the arrangement of the arm rest and the evaporator are neglected . whilst , in the embodiment of the present invention depicted by fig1 the arm rest is attached to the bottom edge 18 of refrigerating device 5 , the fold - down arm rest 8 shown in fig2 is attached approximately in the center of refrigerating device 5 and comprises a substantially u - shaped frame 34 , its length a being ( as in the embodiment depicted by fig1 ) approximately the same as height b of refrigerating device 5 and its width d being ( again , as in the embodiment depicted by fig1 ) approximately the same as width d of refrigerating device 5 , height b and width d of refrigerating device 5 completely occupying the space in back rest 4 usually occupied by known fold - down arm rests . a fold - down or removable cover 7 of said refrigerating device 5 extends substantially over the entire width d of said refrigerating device 5 as well as approximately half of the height b of said device 5 , thereby preventing objects stored in the bottom portion of said device from falling out of said device , even if said cover 7 is opened , and thence providing , as an additional advantage , more safety in the event of an accident . the arrangement depicted in fig2 also saves energy , as it substantially prevents relatively cold air accumulated near the bottom of said refrigerating device 5 from flowing out of said refrigerating device 5 when said cover 7 is opened . said cover 7 is entirely concealed by the base part 13 of the arm rest 8 , said base part 13 comprising an area for placing objects on the upper side ( when said arm rest is folded down ) and upholstery on the lower side ( when said arm rest 8 is folded down ), said upholstery serving as part of the back rest when said arm rest 8 is folded up . the u - shaped borderings 14 and 15 adjoining said base part 13 which may serve as a table when said arm rest 8 is folded down embrace a cut - out area 16 of said arm rest 8 which is entirely filled by preferably heat - insulating upholstery 17 on the front 32 of said refrigerating device 5 when said arm rest 8 is folded up , said borderings 14 and 15 then extending on the sides of said upholstery 17 from the bottom edge 18 of said refrigerating device 5 to the bottom edge 19 of said refrigerating device cover 7 and then being flush with the side wall 20 of said refrigerating device 5 . referring now to fig3 fig3 is a side view indicated by arrow a in fig2 of a refrigerating device 5 similar to the embodiment of the present invention shown by fig2 said device 5 being integrated between the back rests of vehicle seating , with the cover 7 of said refrigerating device 5 being closed and the arm rest 8 being folded up . unlike the embodiments of the present invention shown by fig1 and 2 , the embodiment of the present invention depicted by fig3 through 6 provides for the u - shaped frame 34 to be entirely filled in by a thin plate 23 such as a decorative wooden plate arranged below the upper edge of said frame 34 when arm rest 8 is folded down . said arrangement creates a flat space between the refrigerating device 5 and the arm rest 8 , the refrigerating device 5 and the arm rest 8 , when folded up , said space being fit to accomodate , in a preferred embodiment of the present invention , a thicker and thence better insulating part 7 &# 34 ; of the cover or the front wall of said refrigerating device 5 , the frame 34 also serving as a bordering of said plate 23 which may be used as a table preventing objects on said plate 23 from falling easily over said edge . in the arrangement described herinabove , the upholstery on said frame 34 covers the less insulated outer parts of said refrigerating device 5 where said upholstery has an insulating effect . said frame 34 is also fit to absorb the forces applied by vehicle passenger arms when said frame 34 is used as an arm rest . two supporting devices 21 and 22 preferably arranged along the two side walls of said refrigerating device 5 are attached , by swivelling arrangements , at their one ends to the side walls 20 of said refrigerating device 5 and at their other ends to the u - shaped borderings 14 and 15 respectively of said frame 34 . as the arm rest is folded down , the bottom edge of supporting device 21 rests , substantially in its center , on the upper face of the bottom supporting device 22 , thereby combining an elegant appearance with sturdy support of the arm rest 8 , as neither supporting device 21 nor supporting device 22 enters the empty space between the arm rest 8 and the front wall of refrigerating device 5 . as shown by fig4 the front edge 24 of arm rest 8 moves forward from its position in the back rest 4 depicted in fig3 to an unfolded position , the unattached ends of the u - shaped borderings 14 and 15 moving along the section of a circle represented by a broken line in fig4 . when arm rest 8 has been moved forward , cover 7 may be moved forward around hinge 25 as shown by arrow b in fig4 to open refrigerating device 5 , the upper edge 26 of cover 7 moving along the section 27 of a circle around the axis of hinge 25 as shown by a broken line in fig4 . as depicted in fig5 a refrigeration means 11 may be mounted in trunk 10 of the vehicle closely behind refrigerating device 5 if a base means 28 , such as a base used for the carriage of long goods , is arranged behind the original cut - out for the arm rest 4 . however , such a refrigeration means 11 may be accomodated at any other place in trunk 10 or may also be integrated with refrigerating device 5 . as fig5 also shows , the side walls 20 , the floor 29 and the roof 30 of refrigerating device 5 may be a monolithic structure made preferably from insulating material , said monolithic structure being bolted or otherwise suitably attached to the forward wall 31 of trunk 10 by its rear wall 33 and , as stated above , the refrigerating means 11 may be integrated with or attached to the refrigerating device 5 . the direction of movement of the arm rest 8 shown in fig2 through 6 may also be opposite to the directions shown in said figures . as the figures indicate , the arm rest 8 is preferably relatively flat , thereby occupying little space . the refrigerating device referred to herein may be any cabinet designed for thermal insulation , therefore also allowing food , such as baby food , to be kept warm or to be heated .
