544v! ewwyemzz United States Patent BACK SUPPORT FOR AUTOMOBILES-BACK SAVER Blase Pasquarelli, Bronx, N. Y.
Application December 14, 1955, Serial No. 553,035
7 Claims. (Cl. 155-482) This invention relates to back supports for automobiles or the like.
The lower back, or rather the dorso-lumbar curve of the spine, is normally a forward curve of the spine. Forceful straightening of that curve may precipitate pain in the lower back as well as pains in the legs. Sitting for long periods of time in an automobile, with the car bouncing up and down, will cause strains of the back with straightening of the dorso-lumbar curve. Backache and tiredness will occur which may actually cause physical impairment.
It is accordingly a principal object of the present invention to provide a back support for vehicles or the like which will relieve the above-mentioned strain.
It is another object of the present invention to provide a back support of the above type wherein the vertical movement of the car seat in an up and down direction is partially or totally prevented from passing to the back of the motorist.
It is still another object of the present invention to provide a back support of the above type wherein the back supporting member is adjustable vertically to the convenience of the user.
It is still another object of the present invention to provide a back support of the above type which includes a freely movable sectionwhich rides over a second section mounted upon the car seat which prevents the back of the motorist from absorbing the usual up and down friction of the seat and wherein a back rest supporting the dorsal-lumbar curve of the spine from over-extension is incorporated on the aforesaid freely movable member, said back support being adjustable to the particular individual using the support.
Gther objects of the invention are to provide a back support bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacutre and efficient in use.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a perspective view of a preferred embodiment of the present invention shown in operative use;
Fig. 2 is a side elevational view thereof and shown supporting the motorist with the upper end of the freely movable member released from the inner member and with the back rest in operative position supporting the dorso lumbar curve of the spine from over-extension; and
Pig. 3 is an enlarged detail of Fig. 2, showing the manner in which the freely movable member glides over the inner member to maintain the back of the motorist free from the usual up and down friction of the back of the seat and illustrating the manner in which the back support is slidably mounted on the freely movable member.
Referring now more in detail to the drawing, indicates the usual back supporting portion of a vehicle or automobile seat, substantially as illustrated.
2,831,533 Patented Apr. 22, 1958 faced, preferably pliable material, for example plastic,
leather or other material having similar physical properties. The stationary sheet 11 extends across the front face of the seat 10 and across the upper edge thereof, being mounted th'ereat by means of a pair of laterally spaced, fiat metal clips 12 mounted into the upper edge of the sheet l1, as at 13,- whereby to mount the sheet 11 in the position shown, while at the same time permitting its easy and ready removal therefrom.
A flexible supporting member 14 of Z-shaped cross section (Fig. 3) is suitably secured at one end to the upper front face of the sheet 11, for example by means of heat sealing or other suitable means. The other end of the support 14 is secured to the upper inner face of a second freely movable sheet 15 of the same material as sheet 11, for example by means of heat sealing, a reinforcement or spacer strip 16 being provided intermediate the sheet 15 and accordian-like support 14. A plurality of laterally spaced male snap fastening elements 17 are mounted on the inner face of the front portion of the accordian shaped support 14 and cooperate with a corresponding plurality of laterally spaced female snap fastening elements 18 to retain the movable member 15 in fixed position on the stationary member 11 when not in use, as shown in Fig. 1. In this position the lower edge of the sheet 15 will terminate short of the lower edge of the sheet 11. However, when the snap fastening ele-- 14 to prevent the up and down movement of the seat 10 from being transmitted to the sheet 15, as will be obvious. Thus, when the clips 17, 18 are out of engagement with each other, the support 14 will serve as a shock absorber between the sheet 11 and the sheet 15 whereby to prevent the up and down movement of the seat 10 from being transmitted to the back of the motorist.
In order to support the curve of the spine, namely the dorso-lumbar curve 19 (Fig. 2), a sponge rubber back support or cushion 20 is positioned across the front face of the sheet 15 extending from edge to edge near the lower end thereof by means of the looking or clipping catches 21 suitably secured to the opposite ends thereof and'adapted to resiliently engage the opposite vertical edges of the sheet 15, whereby to permit its slidable adjustment Of course, any other suitable means than the male snap fastening elements 17 and female snap fastening elements 18 may be employed for holding the upper end of the sheet 15 on the upper end of the sheet 11 when the device is not in use without departing from the spirit and scope of the invention. The ends of the accordian-like support 14 may be secured to the sheets 11 and 15 by sutures or other suitable fastening means. Also, the flat hooks 12 for securing the device on the seat 10 may be formed integral with the sheet 11.
It will be seen that the back support 20 is adjustable on the sheet 15 to the convenience and particular requirements of the individual user. The lock clips 21 are of U-shapecl cross section and are adapted to resiliently engage the opposite edges of the sheet 15. When the clips or snap fastening elements 17 are opened, the lower edge of the sheet 15 will extend downwardly several inches below the lower edge of the stationary sheet 11.
When in non-use position, the folded accordian-type support 14- is kept tight and unmovable by the snap fes o toning elements 17, 18. When ready for use, the snap fastening elements are disengaged to allow the two members 15 and 11 to glide freely one over the other. Thus, in an automobile, the movement of the back of the seat 1001. the car is accepted by the first member 11 of the device, and it is not necessarily transmitted to the forward or second part 15. This is especially so, if a small amount of dry dusting powder is sprinkled between the sheets occasionally. The back support 20 may be of foam rubber, or cushioning, or other suitable material. It may be attached in many ways to the front surface of the second member 15 although'the clipping catches 21 are preferred. The cushion 20 is adjustable to the curvature of the. spine 19 by sliding it up or down.
It will now be apparent that there has been provided a device for supporting the dorso-lumbar curve of the spine so as to prevent the same from straightening out and to prevent the precipitation of pain in the lower back and pains in the legs. The accordian-like support 14 will also prevent the up and down vibration of the seat from being transmitted to the sheet and thus to the back of the motorist to further eliminate strains of the back and to eliminate backache and tiredness which may actually cause physical impairment. This is particularly true when sitting for long periods of time in an automobile or other vehicle, for example buses and air planes.
Although the device has been shown in operative use in the drivers seat, it will be readily apparent that it is also adapted to be used in any other seat of the vehicle. Thus, over-extension of the dorso-lumbar curve of the spine is prevented.
Other methods of holding the cushion 20 firmly attached to the sheet 15 may, of course, be employed. However, with the clipping catches 21, it is unnecessary to perforate the sheet 15 and thus weaken it. The edges of the sheet 15 may be reinforced with the semi-rigid strips 22 (Fig. 3). The ends of the strips 22 will be suitably secured to the inner face of the sheet 15 to slidably abut the clipping catches 21 and to limit the upward and downward extreme displacement thereof.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
