Patented Sept. 1, 1931 PATENT orf-FICE UNITED sTATEs CHARLES E. FERREIRA, OF OAKLAND, CALIFORNIA RECLINING CHAIR Application led November 26, 1928. Serial No. 321,910.

tures of constructionand arrangement adapted to provide a more eiiicient chair.

The primary object of the present invention is to provide an improved reclining 25 chair.

Another object is to provide an improved construction which is simple and' positive in its action and in which the operatingr parts are so constructed and arranged as to avoid any possible injury to an occupant or damage to his apparel.

A further object is to provide an improved construction whereby normally the back is positively held in a normal upright position, and which will facilitate the movement of the back of a desired reclining position.

Another object is to provide an improved construction having a positive manually operated actuating means.

A still further object is to provide an improved construction in which the parts are simple and rugged and which cannot ordinari'ly get out of order.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a. part of the present application wherein like characters of reference are used to designate similar parts throughout the drawings and specification and in which- Fig. 1 is a transverse section showing the inner side of one of the side frame members, the seat and upholstery of the back being in- /15 dieated in dotted lines;

Fig. 2 is a broken side elevation, partly in section of the back retaining means ,and indicating themanner in which the/same is moved to release the back;

Fig. 3 is a horizontal section of the chair frame showing in plan the arrangementof Athe back retaining means;

Fig. 4 is a broken vertical section of the chair trame showing a front elevation of the retammg means; and

Fi 5 is a front elevation of a detent mem er. y Y U Referring to the drawings, the'numeral 1V 1s used to designate a pair of side frame members each having leg portions 2 and an up- 60 wardly extending arm portion 3. -A back 4 is pivotally mounted as at 5 between the frame members 1, said back comprising a suitable frame upon which is applied .suitable holster-y 4 and provided with-downwardly 65 disposed extensions 6 at each side of the frame. The extensions 6 are arranged adja-V cent the inner sides of the frame members l and are formed at an angle to the back 4. i such that when the extensions are moved to a normal position against flanges 7 formed u ponthe inner sides of the rearward leg portions 2, the back 'will then be held in its normal upright positief: as shown in Fig. 1 of the drawings.

A pair 01E ratchet bars 8 are pivotally connected tothe lower ends of the extensions 6, said bars being arranged to extend forwardly. 'along the sides of the frame members 1 past detent members 9 secured upon the inner sldes 80 of the frame members 1. The detent members 9 each consist of a hollow body portion having a slot 1l arranged to receive a bar 8, the lower portion of said body being shaped to form a detent 12 arranged to engage any 85 of a plurality of ratchet teeth 18 formed upon the bar 8. The teeth 13 are formed upon the lower edge of the bars 8 in downwardly disposed and forwardly faced position. The bars 8 are normally held by gravity in en- 90 gagement with the detents 12. However, springs 14 are mounted within the upper hollow portion of the body portions 11 to insure a 'positive engagement of the bars with the detents, and to prevent rattling. 95

The forward ends of the bars 8 extend past the detent members. Arms 16 are pivotally mounted adjacent the detent members 9 and Y arranged to engage the ends of the bars 8, said arms preferably .having rollers v17 00 mounted thereon to form rolling contact with the under side of the ends of the bars 8 as shown in Figs. 1 and 2, the arms are preferably secured u on a shaft 18 extendmg between the side tIi'ame members 1 and supported upon suitable bearings formed upon the detent members 9. A lever 19 is mounted in connection with the shaft 18 for actuating the same, said lever preferably being formed integrally with onc of the arms 16 in the form of a bell crank. The lever 19 extends upwardly adjacent the inner side of one of the side frame lnembers 1 and is provided with a slightly offset handle portion 21 adapted to provide a hand hold whereby the lever may be shifted to actuate the shaft 19 and arms 16. A guide 22 is secured upon the member l to limit the movement of the lever 19.

The detent member is provided with a rearward disposed extension 23 arranged to slidably engage a rod 24 extending through said extension and connected to an extension 26 carried by the extensions 6 of the back. Springs 27 are mounted upon the rods 24 andI` arranged to be compressed between the extensions 23 and 26 to exert a pressure operating to normally move the back to its normal upright position.

The detent member 9 is also provided with an extension 28 formed upon its lower end and arranged to form a support for a cross member 30 connecting opposite side frame members 1. A second cross member 31 is secured between the members 1 adjacent the front of the chair, said cross members 29 and 31 forming supports upon which a suitable upholstered seat 32 is supported.

In operation, the back 4 is normally held 1n substantially upright position by the sprinfrs 27, the normal position being defined by t e engagement of the extensions 6 with the flanges 7. The ratchet teeth 13 are so pos1- tioned that the face of the front tooth 13 of each bar 8 will be received in back of the detents 12 to normally prevent the back from being swung rearwardly from its normal position. The ratchet bars 8 are normally held in operative engagement with the detents by gravity, and tlie springs 14 prevent inadvertent disengagement and prevent rattling of the bars within the detent members.

When it is desired to move the back to a reclining position, the occupant of the chair moves the lever 19 rearwardly, thereby swinging the arms 16 upwardly and lifting the ratchet bars 8 out of engagement with the detents 12 as indicated in dotted lines in Fig. 2. As the occupant now rests his weight against the back 4, said back is swung. rearwardly upon its pivot mounting 5 against the pressure of the springs 27, said spring being compressed as the extension 6 is moved forwardly. When the back has been moved to the desired reclining position, the lever 19 the entire is released and the ratchet bar 8 permitted to reengage the detent, one of the more rearwardly disposed teeth of each bar 8 then engaging the detent to prevent further rearward movement of the back. The back will remain in the reclining position so lon as the weight of the occupant is supported t iereon. When the occupant removes l`is weight from the back of the seat, the springs 27 operate to return the seat back to normal position, the ratchet teeth 13 and the detent 12 being provided with inclined surfaces 33 and 34 respeetively whereby the rack may be moved freely rearwardly past the detent. The ratchet bars 8 are provided with ribs 36 formed upon the sides thereof to engage the sides of the detent member 9 and thereby limit the forward movement of the rack bars through the slots 11 and thus limit the rearward inclining of the seat back.

My improved chair is desi ned primarily for installation upon automobile busses and stages. In this connection, my improved chair construction is particularly advantageous as there are no outwardly protruding parts which might cause injury to occupantsk or damage to their apparel or luggage, and structure is compact and easily operated. The chair is of course not restricted to this particular purpose, but is useful for many other purposes.
