  In the present paper, we define the notions of Lorentzian Sabban frames and
de Sitter evolutes of the unit speed space-like curves on de Sitter 2-space
$\mathbb{S}^{2}_{1}$. In addition, we investigate the invariants and geometric
properties of these curves. Afterwards, we show that space-like Bertrand curves
and time-like Bertrand curves can be constructed from unit speed space-like
curves on de Sitter 2-space $\mathbb{S}^{2}_{1}$ and hyperbolic space
$\mathbb{H}^{2}$, respectively. We obtain the relations between Bertrand curves
and helices. Also we show that pseudo-spherical Darboux images of Bertrand
curves are equal to pseudo-spherical evolutes in Minkowski 3-space
$\mathbb{R}^{3}_{1}$. Moreover we investigate the relations between Bertrand
curves and space-like constant slope surfaces in $\mathbb{R}^{3}_{1}$. Finally,
we give some examples to illustrate our main results.
