The ornamental design for a chair back, as shown and described.

FIG. 1 is a front elevational view of the chair back showing my new design;

FIG. 2 is a rear elevational view thereof;

FIG. 3 is a perspective view from one side thereof;

FIG. 4 is a side view thereof, the other side elevation being identical thereto;

FIG. 5 is a top elevational view thereof;

FIG. 6 is a bottom elevation view thereof;

FIG. 7 is a cross section taken generally along line VII--VII of FIG. 1;

FIG. 8 is a cross section taken generally along line VIII--VIII of FIG. 1;

FIG. 9 is a cross section taken generally along line IX--IX of FIG. 1;

FIG. 10 is a cross section taken generally along line X--X of FIG. 1; and,

FIG. 11 is a cross section taken generally along line XI--XI of FIG. 1.

The center core of the backrest depicted in FIGS. 7 through 11 by means of diagonal lines and small fragmented circles is understood to represent resilient foam material. The broken lines shown below the headrest in FIGS. 1 and 3 represent stitching. The broken lines showing the remainder of the chair in FIGS. 1 through 6 are for illustrative purposes only and form no part of the claimed design. FIGS. 7 through 11 have been shown on an enlarged scale with respect to the other views.
