BY 63am ATTORNEYS VEHlCULAR-SAFETY CHAIR BACKGROUND AND SUMMARY The usual vehicular chair, as, for example, in a bus, is provided with a top rail providing a hand grip, but this rigid structure presents a hazard in the case of a sudden deceleration of the vehicle, and also the use of the hand grip behind the occupant of the seat is an annoyance to the passenger. Ash trays mounted upon the seat back also present a hazard and are very unattractive in appearance. It is also of great importance to provide yieldable means to protect a person being thrown forwardly in the case of sudden deceleration of the vehicle and who comes into contact with the rear seat back in front of him. A problem has also been presented with respect to the snuffing of cigarettes since the cigarette is often pressed against plastic, fabric, or other materials of the seat and injure the material.

I have discovered that a panel of flexible or yieldable material, such as plastic, thin metal, etc., may be employed by supporting it upon the back of the chair frame to provide a chamber or space between it and the seat back, the seat back being preferably high and carrying high cushions. Such a panel may be cut away along the inner corner or portion adjacent the aisle to provide a hand grip which is thus not only concealed but also in a position where the wrist and lower portion of the arm in addition to the hand grip afford a means for checking forward movement of the passenger. Also, the space is utilized for providing an ash channel which may be extended downwardly to a knee recess therebelow and provided with a movable closure. Further, by utilizing a supporting panel below the arm rest, the panel being formed of metal, a relatively broad area is provided for cigarette snuffing.

DETAILED DESCRIPTION The vehicular chair 20 consists of legs 21, bucket seats 22, high back cushions 23, a wall panel 24, arm rest panel 25 a decorative aisle panel 26 with a metal insert panel 27, an arm rest 28 and a high plastic or yieldable metal back panel 29 with knee recesses 30, a recessed hand grip 31, and an ash tray channel 32 having a closure-equipped bottom 33 in one of the knee recesses 30.

As shown best in FIGS. 6-9, the back cushions 23 and outer back panel 29 are attached to a tubular steel frame 34. The outer back panel 29 may extend only across the upper portion of the chair back, but I prefer to have the panel extend downwardly substantially along the entire back of the chair and provided with knee recesses 30 since one of the knee recesses provides also a means for emptying the ash tray. At the recesses, the back panel comes into contact with the rear side 35 of the cushions 23, but above the knee recesses there is a small space or chamber 36 which makes possible the hand grips 31 and the ash tray channel 32.

FIGS. 4 and 6 show a hand grip which is molded right into the plastic back panel and this hand grip 37 needs no further support or means of attachment. It may touch the back 35 of the seat cushion, but need not do The metal hand grip 31 shown in FIGS. 3 and 9 may be provided with a metal flange 38 welded to flange 39 which in turn is welded to the top tubular rail 34. If desired, the members 38 and 39 and the rail 34 may be connected by screws, rivets, welding, or any suitable means.

The aisle end consists of a tubular frame 40 covered first by a plastic inner panel 41, then the plastic outer panel 26, covered by the metal panel 27 and capped with a plastic arm rest 28. The entire arm rest structure is generally in the shape of the letter C, and in this structure the metal panel 27 forms the outer exposed surface and a support extending between the lower and upper portions of the arm rest member. The metal cigarette butt snuffing panel 27 may be cemented to the plastic panel, as shown in FIG. 10, or it can be made to snap into grooves 42 in the outer plastic panel, as illustrated best in FIGS. 11 and 12. The grooves may be made by the addition of a slight ridge 43 to the plastic panel.

From the foregoing, it will be observed that the rear panel 29, is preferably formed of plastic material but which may, if desired, be formed of thin metal or other material which will yield under impact, provides a safety measure in itself, while at the same time the spacing of this panel from the back cushions enables the hand grip to be substantially concealed and formed as a part of the rear panel. Similarly, the panel provides for the ash channel which opens into a knee recess below so that the closure of the recess is exposed for opening to clean the channel. Thus the anchoring of the rear panel to the sturdy metal frame 34 of the seat back provides the hand grip support, the ash channel support, and is further yieldable itself as a means for protecting the passenger in the seat to the rear of the seat back illustrated.

While in the foregoing I have set out a specific structure in considerable detail for the purpose of illustrating a preferred embodiment, it will be understood that such details may be varied widely by those skilled in the art without departing from the spirit of my invention.

lclaim:

1. A vehicle chair adapted to extend to one side of a vehicle aisle, comprising a high back frame, a high back cushion carried by said frame, a back panel of yieldable material anchored to and extending across the upper rear portion of said frame in spaced relation to said cushion to provide a closed chamber therebetween, a hand grip in said back panel adjacent said aisle and opening into said closed chamber; said back panel providing a forwardly-extending knee recess in the lower portion thereof; and an ash receptacle in the upper portion of said back panel and recessed within said chamber and including a downwardly-extending channel communicating with said knee recess, whereby ashes or debris deposited in said receptacle will flow under gravity through said channel.

2. The structure of claim 1 further comprising a movable closure at the bottom of said channel and accessible through said knee recess for removing debris from said channel.

3. The structure of claim 2 wherein said hand grip is in the upper comer of the panel adjacent said aisle.

' 4. The structure of claim 2 further comprising a C- shaped arm rest secured to said frame adjacent the aisle end of said seat; and a snuffer plate extending in supporting relation between upper and lower horizontal portions of said C-shaped arm rest.

Claims

3. The structure of claim 2 wherein said hand grip is in the upper corner of the panel adjacent said aisle.

4. The structure of claim 2 further comprising a C-shaped arm rest secured to said frame adjacent the aisle end of said seat; and a snuffer plate extending in supporting relation between upper and lower horizontal portions of said C-shaped arm rest.
