ARM REST Filed May 20, 1964 2 Sheets-Sheet 2 www TTRNEY United States Patent() 3,279,853 ARM REST Lee E. Cromwell, Clawson, and Gary L. Engel, Flatrock, Mich., assignors to General Motors Corporation, Detroit, Mich., a corporation of Delaware Filed May 20, 1964, Ser. No. 368,869 6 Claims. (Cl. 297-412) This invention relates to vehicle body arm rests and more particularly to a vehicle body arm rest having a base and a cushion assembly.

`One feature of this invention is that the base is constructed and arr-anged so as to be used on body panels of opposite hand. Another feature of this invention is that the base is symmetrical about the longitudinal center line thereof so as to be used on body panels of opposite hand. A further feature of this invention is that the base includes longitudinally spaced mounting portions and an intermediate hand grip portion, with the mounting portions including means for mounting the base on the body panels and means for securing the cushion assembly t-o the base, with both said means being symmetrical about the longitudinal center line of the base. Yet another feature of this invention is that the hand grip portion includes a finger receiving pocket located to each side of the longitudinal center line of the base and opening laterally thereof. Yet a further feature of this invention is that the mounting portions include recesses adapted to receive and to be secured to mounting means on the cushion assembly.

These and other features of the invention will be readily apparent from the following specification and drawings wherein:

FIGURE 1 is a perspective view of a vehicle body arm rest according to this invention mounted on a body panel;

-FIGURE 2 is an enlarged sectional view taken generally along the plane indicated by line 2-2 of FIGURE 1;

FIGURE 3 is an enlarged sectional view taken generally along the plane indicated by line 3 3 of FIGURE l;

FIGURE 4 is an exploded perspective view of the arm rest shown in FIGURE l;

FIGURE 5 is a View taken generally along the plane indicated by line 5-5 of FIGU- RE 2; and A FIGURE 6 is a view taken generally along the plane indicated by line 6-6 of FIGURE 2.

Referring now to FIGURES 1 and 4 of the drawings, the arm rest includes a base or support 10 and a cushion assembly 12 which is secured to the base after the base has been mounted on a vehicle body panel 14, as will be described. The base 10 includes means for mounting a paddle type inside door handle or operator 16 which is connected to a door latch in a conventional manner lto release the latch upon movement of the handle. The arm rest need not incorporate such a handle unless desired, and the handle forms no part of this invention.

The base 10 includes spaced

mounting portions

18 and 20 and an intermediate hand g-rip portion 22. The mounting portion 18 includes a base Wall 24, like arcuate upper and lower or

side Walls

26 and 28, and

end walls

30 and 32. As shown in FIGURE 5, a plurality of transverse Webs or ribs 34, 36 and 38 interconnect the

Walls

26 and 28. The webs 34 and 36 are further interconnected by longitudinal webs or ribs 40 and 42. The apertured inclined Walls 44 and 45 of a wedge or prisrnoid 46 are joined to the walls 40 and 42 at the bases thereof. A mounting clip 48 surrounds the Walls 44 and 45, FIG- Patented Oct. 18, 1966 URE 3, being provided with openings aligned with the apertures of the Walls, and with olfset tangs or end por-tions 50 which extend through openings in each of the Walls 44 and 45 so as to releasably retain -the mounting clip in place.

The transverse webs 36 and 38 and wall 32 are interconnected by longitudinally extending webs or ribs 52 and 54, with the intersection of the Webs 52 and 54 and the web 38 including columns or tubular portions 56 and 58, respectively, which open to the outer or front side of the base 10 through Wall 24 to a generally vertically extending recess or pocket 59 of the base 10.

The mounting portion 20 is `similar to the mounting portion 118 and includes a base `wall 60, upper and lower or side Walls 62 and 64, and end Walls 66 and 68. As shown in FIGURE 5, a plurality of transverse webs or ribs 70, 72, 74, and 76 interconnect the walls 62 and 64 of this mounting portion. The walls 72 and 74 correspond lto the Walls 34 and 36 of the portion 18 and are interconnected by longitudinal Webs or ribs 78 and 80 which correspond to the webs 40 and 42. The apertured inclined Walls 82 and 84 of a Wedge or prismoid 86, which corresponds to the wedge 46, are joined to the walls 78 and 80 at the bases thereof. A clip 48 surrounds the Walls 82 and 84 and is secured thereto in the same manner as to Walls 44 and 45.

The webs 74 and 76 and the wall 66 of portion 20 are interconnected by longitudinally extending Web-s or ribs `88 and 90, with the junctions of these Webs with the web l76 including columns or tubular portions 91 and 92, respectively, which open to the front face or side of the portion 20, to a generally vertically extending recess or pocket `94. Webs 88 and 90 correspond to Webs 52 and 54 and columns 91 and 92 correspond to columns 56 and 58, respectively. The Web is cut away to provide for the Vmounting of the paddle handle 16 Wit-hin the portion 20 in a conventional manner and the end Wall 68 is cut away to permit the handle to rotate relative t-o the ba-se 10.

It Will be noted that the pairs of tubular columns 56 and 91 and 58 and 92 are located on opposite sides of the longitudinal center line of the base 10 and equidistant therefrom. I-t will further be noted -that the pairs of inclined apertured Walls 44 and 82 and 45 and 84 are also so located on opposite sides of the longitudinal center line of the base 10 so that both the mounting means for the base on the body panel and the mounting means for securing the cushion assembly to the base are symmertically arranged. Thus, it makes no difference Whether the base 10 is mounted on a right-hand or a left- -hand body panel and the same base can be used for both such panel-s by merely rotating the base `through 180, as will be explained.

The hand grip portion 22 of the -base 10 includes a base wall 95 which is located intermediate the

Walls

24 and 60 and is joined to the end walls 30 and 66 of the

housing portions

18 and 20, respectively, as can be seen in FIGURE 5. Wall 95 is intermediately grooved at 96 with the base of this groove being located at the longi tudinal center line of the base 10 and in longitudinal alignmen-t with the junctures of walls 44 and 45, and 82 and 84. Portion 22 further includes a base wall 100, FIG- URE 4, which is located Iin lateral parallel spaced relationship to the Wall 95 and is also joined to the walls 30 and 66 of the

portions

18 and 20, respectively, as Well as being located generally coplanar with the

base walls

24 and 60 of these portions. As shown in FIGURES 4 and 5, a lateral web or wall 102 interconnects the

walls

94 and 100 and the walls 30 and 66 and cooperates therewith in providing oppositely opening pockets or finger-receiving portions 104. The wall 102 is located coplanar with the plane of the longitudinal center line of the base 110. The front face or surface of the wall 95 may be {grooved or otherwise decorated as desired, as shown in FIGURES 1 and 4.

The base is mounted on the body panel 14 by inserting screws or bolts 106 through the columns 56 and i91 or 58 and 92 into threaded engagement with tapped (openings of a body inner panel 108 which forms the 'foundation or base member for the trim panel 110. As can be seen in FIGURE 2, the recesses or pockets 59 and 94 permit the heads of the bolts 106 to be located within the plane of the

base walls

24, 100 and 60 of the base 10. Since the columns 56, 58, 91 and 92 are located equidistant from the longitudinal center line of the base 10, it makes no difference whether the base is mounted on a right-hand or left-hand body panel.

The cushion assembly 12 generally -comprises a U- shaped metal base or core member 112 located within a cast plastic cushion 114 of suitable material, such as polyurethane. Cushion 114 is bonded to 'an outer seamless shell 116 of suitable trim material such as vinyl, which yis formed as a one-piece element in a suitable manner, such as by rotational casting. The cushion 114 may be foamed in place within the shell 116 after the core member 112 has been first located within the shell. At two places, the inboard leg 118 of the member 112 is offset outwardly at 120 from its normal plane, as shown in FIGURES 3 and 6, and apertured at 122. The bases 124 of the generally U-shaped odset portions 120 are adapted to abut or be juxtaposed to the pairs of inclined walls 44 and 82 or 45 and 84 of the base 10 depending upon whether the base is used as a right-hand base or as a left-hand base. As shown in FIGURE 3, the offset portions 120 lit within the recesses defined by the prismoids 46 and 86 and the cushion assembly 12 is secured to the base 10 by sheet metal type screws which extend through the openings in the inclined walls into threaded engagement with the clips 48. The cushion assembly 12 is suitably cored or apertured at two places at 126 to provide inclined columns or openings permitting the screws 118 to be mounted in place.

If the arm rest is used as a left-hand arm rest as shown in FIGURES l, 2 and 3, the bases 124 of the offset portions 120 will be abutted against the inclined walls 44 and 82 and be secured thereto. as a right-hand arm rest the base 10 will be rotated 180 so that the bases 124 of the offset portions 120 will be abutted against the inclined walls 45 and 84 and be secured thereto. Since the base 10 is symmetrical about the longitudinal center line thereof, it need only be rotated through 180 or turned upside down as previously explained, so as to be used for either a right-hand or a lefthand part. However, the cushion assembly 12 is not symmetrical about the longitudinal center line thereof but is symmetrical about a vertical transverse axis or plane so that the cushion assembly must be removed from the base 10 and turned end for end if it is to be used for parts of opposite hand.

Thus, this invention provides an improved vehicle body arm rest.
