BALL, OF DETROIT, MICHIGAN, :ASSIGNOR T BRIGGS MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN ADJUSTABLE SEAT ASSEMBLY Application filed May 26,

This invention relates to seat assemblies and more particularly to adjustable seats adapted to be used in connection with vehiole bodies.

One of the primary objects of this invention is to provide a seat of the above type capable of being adjusted as a unit longitudinally of the vehicle so as to vary the distance between the seat and controls of the vehicle.

Another object of this invention is to provide mechanism for adjusting the seat which is inherently self looking so that the seat is rigidly held in its various positions of adjustment.

A further object of the present invention resides in the peculiar connection between the seat and support therefor which in addition to permitting an unobstructed slid ng movement of the seat relative to its support, renders possible detaching the seat from the support.

A still further object of this invention is to provide means for guiding both ends of the seat in a true rectilinear path and thereby prevent a twisting or lateral movement of the seat relative to its support.

Another novel feature of this invention is attributed to the ease and rapid ty with which the seatmay be assembled within the body and the minimum number of parts employed for accomplishing adjustability of the seat.

Other objects and advantages of the present invention are attributed to the peculiar construction of the seat and operating mecha nism therefor which will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein:

Figure 1 is a top plan view of a seat as sembly embodying my invention:

Figure 2 is a vertical sectional view through the seat assembly:

Figure 3 is an enlarged fragmentary top plan view of the seatassembly;

Figure 4 is a sectional view taken on the line 44 of Figure 3;

Figure 5 is a detail perspective view of one 50 of the clamp plates;

Figure 8 is a sectional View taken on the line 8-8 of Figure 1;

Figure 9 is a sect'onal' View taken on the line 99 of Figure 1;

Figure 10 is a sectional view taken on the line 10 -10 of Figure 1'; I r

Figure '11 is a sectional view taken on the line 1111 of Figure 1 Figure 12 is a sectional view taken on the line 1212 of Figure 1.

Referring now to the drawings, 1 is the flooring and 2 is an adjustable seat of a vehicle body. As shown, the flooring 1 is constructed of sheet metal and has a pair of laterally spaced substantially parallel upwardly embossed channel portions 3' constituting slides for the seat 2, and a base 4 of the latter is constructed of sheet metal and has a pair of similarly spaced upwardly embossed channel portions 5 that extend longitudinally of and straddle the slides 3.

6 are transversely curved wear plates of brass between the slides 3 and seat portions 5 and constituting bearings for said portions, and 7 are transversely curved clamp or retainer plates extending longitudinally and straddling the seat embossed portions 5. 8, 9 and 10 respectively are aligned circular openings in the embossed portion 3 and plates 6 and 7 respectively, and'll are slots extending longitudinally of the seat embossed portions 5 in alignment with the openings 8, 9 and 10 respectively. 12 are bolts extending through the openings 8, 9, 10 and intermediate slot 11, and 13 are nuts engaging the bolts 12 above the plates 7 and cooperating therewith to hold the seat embossed portions 5 upon the floor embossed portions 3.

Thus with this construction the bolts 12 and nuts 13 remain stationary while the seat base 4 slides on the plates 6 between the embossed portions 3 and plates 7.

For moving the seat longitudinally of the slides 3 I have provided a screw 15 that is swivelled in a bracket 16 rigid with the seat and that threadedly engages a nut 17 mounted between substantially parallel arms 18 of a floor bracket 19. As shown, the screw 15 is at approximately the center of the seat and is provided at its forward end in advance of the seat with an operating wheel 19. Preferably, the wheel 19 is secured to the screw by means of a bolt 20. Washers 21 and 22 are provided about the screw upon opposite sides of the bracket 16, and a relatively large opening 23 is provided in the seat to permit free movement of the screw therein. The brackets 16 and 19 may be any suitable construction. Preferably the bracket 16 extends substantially parallel to the forwardly projecting flange 24 of the seat base and has oppositely extending vertical flanges 25 and 26 respectively at its opposite ends secured to vertical flanges 27 and 28 respectively of the seat base. In the present instance the vertical flange 25 constitutes the bearing for the screw. The bracket 19 has a flat base 29 rigidly secured to the flooring 1 and supporting the arms 18.

Thus, from the foregoing, it will be readily apparent that rotation of the wheel 19 will cause the seat to move longitudinally of the slides 3, and due to the engagement of the screw 15 with the nut 17 the seat will remain in any adjusted position.

While it is believed that from the foregoing description the nature and advantages of the present invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

In combination, 'a sheet ofmetal constituting a portion of the flooring of an automobile and having an upwardly extending channel shaped embossed portion, a seat base having a channel shaped embossed portion extending longitudinally of and straddling the embossed portion aforesaid, a wear plate between said embossed portion, a clamp plate on the embossed portion of the seat base, and a connection between said clamp plate, seat base, wear plate and sheet of metal including stationary means rigid with the sheet of metal;

In testimony whereof I aflix my signature.

ALBERT P. BALL.
